Ikea 804621671A dishwasher Parts

Replacing the drain hose on an Ikea dishwasher model 804621671A typically costs $33 to $60 for the hose, plus $0 to $200+ for labor depending on access, installation style, and local service rates. If the hose is kinked or leaking, replacement is often the fastest fix.

Typical cost breakdown

• Part (drain hose): usually the main cost for a DIY repair
• Labor (if hired): commonly 1 hour, sometimes more if the dishwasher must be pulled out
• Small extras: hose clamp, zip ties, or a new high loop/air gap connection if needed

Scenario	What you pay for	Typical total
DIY replacement	Hose (and possibly a clamp)	$33 to $60
Service call	Hose + labor + trip/diagnostic	$120 to $300+

What we recommend for model 804621671A

Use the correct hose and fix the root cause so the new hose does not fail early.

• Confirm the routing matches the 804621671A owner’s manual (high loop or air gap setup, depending on your installation)
• Replace the hose if it is split, soft, crushed, or permanently kinked
• If the dishwasher “does not drain properly,” check for a kinked hose and make sure the cycle is not paused (common causes noted in the manual)
• If connected to a food disposer, make sure it is empty and the disposer inlet knockout plug was removed

Model-matched part to use

For this model, the drain hose listed for replacement is:

• Dishwasher drain hose 807117001

Why it matters

A restricted or leaking drain hose can cause poor draining, standing water, odors, and potential cabinet damage. The manual also notes that proper draining depends on correct drain setup (including keeping any countertop drain air gap clean, if your installation uses one).

To connect the drain hose on your Ikea dishwasher model 804621671A to a sink drain, route the hose to the sink drain tailpiece (or garbage disposer inlet), slide it fully onto the drain port, and secure it with a hose clamp. Form a high loop under the countertop so the dishwasher drains reliably.

Connection options (sink drain vs. disposer)

• Sink drain tailpiece (branch inlet): Connect the hose to the small side port on the sink drain pipe.
• Garbage disposer: Connect the hose to the disposer’s dishwasher inlet.
• Air gap (if used): Keep it clean so the dishwasher drains properly (the air gap is mounted on the countertop and is not part of the dishwasher).

Setup	Where the hose connects	Common “gotcha” to avoid
Sink drain tailpiece	Tailpiece branch inlet	Loose clamp or no high loop
Garbage disposer	Disposer dishwasher inlet	Knockout plug not removed
Air gap (optional/required in some areas)	Dishwasher hose to air gap, then to drain/disposer	Clogged air gap causing slow drain

Steps we recommend

• Turn off power at the breaker before working under the sink.
• Route the hose with no kinks and leave enough slack for vibration.
• Create a high loop (as high as possible under the counter) and secure it.
• Push the hose fully onto the drain port, then tighten the clamp.
• If connected to a disposer, make sure it is empty and the knockout plug in the disposer inlet has been removed.
• Run a short cycle and check for leaks and proper draining.

Parts that commonly get replaced during a drain hookup

If the existing hose is brittle, leaking, or too short, replacement is usually the cleanest fix.

• Dishwasher drain hose 807117001
• Dishwasher hose clamp 154380601

Why it matters

A correct drain connection (especially the high loop or air gap) helps prevent dirty sink water from backflowing into the tub and reduces “won’t drain” symptoms like standing water at the end of the cycle.

For model-specific routing notes and illustrations, follow the 804621671A owner’s manual.

Yes, replacing the drain pump on your Ikea dishwasher model 804621671A is usually worth it when the dishwasher is otherwise in good shape and the problem is limited to draining. If the unit has multiple symptoms (leaks, no heat, repeated electrical issues), replacement can make more sense than stacking repairs.

Quick decision checklist

• The dishwasher completes wash but leaves water in the tub.
• The drain hose is not kinked and the disposer knockout plug is removed (if connected).
• The filter and sump area are clear of debris.
• The door latches and the cycle is not paused.
• You are not seeing multiple unrelated failures (for example, not draining plus not heating plus leaking).

Rule out common “not draining” causes first

The manual’s troubleshooting steps for poor draining focus on installation and clogs, not just the pump. Before buying parts, we recommend:

• Confirm the cycle is complete (not paused).
• If connected to a food disposer, make sure it is empty.
• Check that the disposer inlet knockout plug was removed.
• Inspect the drain hose routing for kinks or a sag that traps water.
• Clean the filter area so water can reach the drain path.

For model-specific safety and service guidance, follow the steps in the 804621671A owner’s manual.

When a drain pump replacement is the right fix

A drain pump is a strong suspect when you hear humming but get little or no drain flow, or when the dishwasher drains intermittently after you have cleared hoses and filters.

Model-matched part to consider: Drain pump a A00126401.

Cost vs. value comparison

Situation	Usually worth replacing the drain pump?	Why
Drains poorly, hoses and filter are clear	Yes	Likely a single-point failure
Multiple major issues at once	No	Repair costs add up quickly
You can DIY safely	Yes	Labor savings improve value
You need a technician for everything	Depends	Labor can exceed the value of an older unit

Why it matters

A weak or failed drain pump can leave dirty water in the tub, cause odors, and stop the dishwasher from finishing a cycle properly. Fixing the drain system restores normal operation and helps prevent repeat clogs.

On the Ikea dishwasher model 804621671A, code 40 (often shown as I40) points to a clogged filter that is restricting water flow. Cleaning the filter and checking the sump area typically clears the code and restores normal washing and draining.

What to do first (quick fix)

• Turn the dishwasher off, then cancel/drain if your model allows it.
• Remove the lower rack and take out the filter assembly.
• Rinse the filter under hot water; scrub with a soft brush to remove grease and debris.
• Check the sump area for glass, labels, bones, or food chunks.
• Reinstall the filter fully seated and locked, then run a short rinse cycle.

For the exact filter removal and reinstall steps for your model, follow the 804621671A user manual.

Parts that commonly relate to code 40 symptoms

If the filter is clean but the dishwasher still struggles to circulate or drain, these parts are commonly involved:

• Dishwasher filter 5304532206 (if the filter is damaged or won’t lock in place)
• Drain pump a A00126401 (if water remains in the tub after the cycle)
• Dishwasher drain hose 807117001 (if the hose is kinked or restricted)

Symptom guide

What you notice	Most likely cause	What we recommend
Code 40 appears mid-cycle	Filter packed with debris	Clean filter and sump, rerun cycle
Poor cleaning, gritty residue	Restricted circulation from clogged filter	Clean filter, verify spray arms spin freely
Standing water in bottom	Drain restriction or weak drain pump	Check hose routing, then evaluate drain pump

Why it matters

A clogged dishwasher filter can reduce wash pressure, leave soil on dishes, and trigger drain or circulation faults. Keeping the filter clean helps protect the pump and motor assembly and keeps cycle performance consistent.

On the Ikea dishwasher model 804621671A, the filter area is on the bottom of the tub, centered under the lower spray arm. You access it by pulling out the lower rack and working in the round filter area where wash water collects and drains. See the 804621671A owner's manual for the exact removal steps for your version.

How to find it (quick steps)

• Turn the dishwasher off and let the water cool.
• Pull the lower rack out.
• Look at the center of the tub floor under the lower spray arm.
• Identify the round filter area (this is where the dishwasher fills to cover the filter area).
• If your model has a glass trap in the center, use its handle to unlock and lift it out.

What you will see in the filter area

Many Ikea-built dishwashers use a filter area that includes a self-cleaning filter plus a center glass trap designed to catch debris like broken glass.

Item in the tub bottom	Typical location	What it does
Filter area	Center bottom of tub	Screens soil so it can be pumped out
Glass trap (if equipped)	Center of the filter area	Collects glass, bones, pits
Overfill protector/float	Left front corner	Helps prevent overfilling

Cleaning and maintenance tips

• Wipe out any visible debris in the center filter area.
• Rinse the glass trap (if equipped) and reinstall it fully snapped in place.
• Make sure the overfill protector moves up and down freely.
• If you notice poor cleaning, check for buildup and confirm the lower spray arm spins freely.

Why it matters

A blocked filter area or glass trap can reduce water flow through the spray arms, which leads to poor cleaning and can contribute to draining problems. Keeping the tub bottom clear helps the pump move water and soil the way the cycle is designed.

If your Ikea dishwasher model 804621671A is not working, the most common causes are a power or start issue (breaker, door not latched, cycle not selected correctly), a water supply issue, or a drain problem such as a kinked drain hose or a clogged filter or trap. Use the checks below to pinpoint the failure fast; see the 804621671A owner's manual for model-specific operating steps.

Quick checks (most fixes)

• Confirm the circuit breaker is on (or replace a blown fuse).
• Make sure the water supply valve is fully open.
• Close the door firmly until it latches.
• Select a cycle, then press START/CANCEL.
• Make sure Delay Start is not set.
• Let the cycle finish; a pause can be normal when switching spray arms.

If it won’t drain or has water left in the tub

Water left in the bottom of the tub after a completed cycle is not normal; it points to a draining problem.

• Check the drain hose for kinks; replace it if it is damaged (see dishwasher drain hose 807117001).
• If connected to a garbage disposer, run the disposer and make sure the disposer inlet knockout plug was removed.
• Clean and reinstall the filter and trap correctly (clogs here commonly stop draining).
• If the dishwasher hums but won’t pump out, the drain pump can be the issue (see drain pump a A00126401).

If it has power but won’t run

Use this sequence to narrow it down:

What you see	What it usually means	What to do next
Lights on, no wash action	Start sequence or door latch issue	Re-latch door; reselect cycle; press START/CANCEL
No lights	Power supply problem	Check breaker, outlet, wiring
Starts then stops with water in tub	Drain restriction	Check hose, filter, disposer connection

Why it matters

A dishwasher that will not start is often a simple control or latch condition, but water left in the tub can lead to odors and poor cleaning. Catching a kinked hose, clogged filter, or weak drain pump early prevents repeat failures.

On the Ikea dishwasher model 804621671A, a “dead” or unresponsive control panel is usually caused by a door that is not fully latched, a tripped breaker/fuse, or the controls being locked (Child Lock). Start by restoring power, latching the door firmly, then unlock the controls and restart the cycle.

Quick checks (most common fixes)

• Make sure the door is closed and latched; the dishwasher will not run or accept selections if the latch is not engaged.
• Check the home circuit breaker or fuse; this dishwasher is designed for 120V, 60Hz on a 15-amp circuit (often 20-amp if connected with a food disposer).
• If the panel lights are on but buttons do nothing, Child Lock may be enabled.
• Press START/CANCEL after selecting a cycle and options.
• If Delay Start is set, the dishwasher can look “not responding” until the delay expires.

Unlock the control panel (Child Lock)

The manual describes a control lock that prevents new selections.

To unlock:

• Latch the door.
• Press and hold OPTIONS for about 3 seconds to toggle the lock off.

For the exact button layout and indicator light behavior, use the 804621671A owner’s manual.

When it points to a part problem

If power is good and the controls are unlocked but the panel still will not respond, these parts are common suspects:

Symptom	Likely area	Example part to check
No response from any keys, intermittent operation	User interface or wiring	Dishwasher user interface 5304517207
Random behavior, won’t start even when latched	Main control	Dishwasher electronic control board 5304531745
Won’t run because it “thinks” the door is open	Door latch circuit (often in harness)	Harness/door latch wiring (model-specific)

Why it matters

The control panel is tied into safety interlocks (door latch and control lock). If the dishwasher does not detect a safe, latched door or if Child Lock is on, it will block operation to prevent leaks and unintended starts.

Your Ikea dishwasher model 804621671A usually will not drain because the drain path is blocked (filter or hose), the drain hose is kinked, or the dishwasher is connected to a garbage disposer with the knockout plug still in place. Start with the simple checks in the 804621671A owner's manual.

Quick checks that fix most no-drain problems

• Confirm the cycle is truly finished and not paused.
• If you drain into a food waste disposer, make sure the disposer is empty.
• Verify the disposer inlet knockout plug was removed.
• Inspect the drain hose for kinks or crushing behind the unit.
• Clean and reinstall the glass trap and filter correctly.

Step-by-step troubleshooting (in a safe order)

1. Cancel and restart: If the door was opened mid-cycle, restart the cycle correctly so the unit can complete the drain.
2. Check the disposer connection: A blocked disposer inlet stops draining even when the dishwasher pump is fine.
3. Inspect the drain hose routing: Look for a kink, sag, or pinch point; straighten the hose.
4. Clean the filter area: Remove debris from the filter and glass trap area so water can reach the drain pump.
5. Listen during the drain portion: A humming sound with no water movement often points to a blockage; silence can point to an electrical or pump issue.

Parts that commonly solve a drain issue

If the drain path is clear and the dishwasher still leaves water in the bottom of the tub, these parts are common fixes for model 804621671A:

Symptom	Most likely cause	Part to consider
Water remains in tub, hose is clear	Drain pump not moving water	Drain pump a A00126401
Slow drain or leaks at hose connection	Split or restricted drain hose	Dishwasher drain hose 807117001
Overfilling then poor draining behavior	Float stuck or float switch failing	Dishwasher float switch 154773201

Why it matters

Water left in the bottom of the tub after a completed cycle is not normal; it leads to odors, poor cleaning, and can cause the next cycle to start with dirty water. Restoring proper drain flow protects the pump, motor, and control system.
