Ikea 804621670A dishwasher Parts

Yes. On the Ikea dishwasher model 804621670A, we can usually replace many common parts at home if you shut off power and water first and follow the safety steps in the 804621670A owner's manual. Simple mechanical items are the best DIY wins; electrical and leak-related repairs take more care.

What you can usually replace yourself

• Dishwasher filter (cleaning or swapping)
• Drain hose (if it’s accessible and not hard-plumbed)
• Lower rack rollers and some rack hardware
• Detergent dispenser (door not opening, broken latch)
• Water inlet valve (if you’re comfortable with basic plumbing)

Safety steps we follow before any repair

The manual calls out key precautions: disconnect electrical power before servicing, keep panels in place during operation, and avoid touching the heating element during or right after a cycle.

• Turn off power at the breaker (dishwasher must be grounded; use the correct circuit)
• Shut off the water supply valve
• Pull the unit only as far as needed; protect the floor and hoses
• Keep a shallow pan and towels ready for water in lines
• Take photos of wire connections and hose routing before removal

Parts that are DIY-friendly for this model

Repair type	Typical difficulty	Example part for 804621670A
Drain issues (pump or hose)	Medium	Drain pump a A00126401, dishwasher drain hose 807117001
Not drying / no heat	Medium	Dishwasher heating element 154825001
Not filling	Medium	Dishwasher water inlet valve 5304525044
Poor cleaning (maintenance)	Easy	Dishwasher filter 5304532206

When we recommend a technician

Some repairs are still doable, but we treat them as “advanced” because mistakes can cause leaks, electrical damage, or repeat failures.

• Control and wiring diagnostics (for example, dishwasher electronic control board 5304531745 or harness issues)
• Recurring leaks from the sump area (often involves seals and precise reassembly)
• Anything requiring extensive disassembly or testing live voltage

Why it matters

DIY replacement can restore cleaning, draining, and drying performance quickly, but dishwashers combine water, heat, and electricity. Following the manual’s shutoff steps and using the right replacement part helps prevent leaks, shocks, and repeat breakdowns.

Most Ikea dishwashers, including model 804621670A, typically last 10 to 12 years with normal household use and basic maintenance. Ikea’s guarantee period is 5 years for many models (some lines are 2 years), which is separate from expected service life; see your 804621670A owner's manual for the guarantee terms and care guidance.

Typical lifespan and what affects it

A dishwasher’s life depends more on water quality, loading habits, and maintenance than the badge on the front.

• Hard water speeds up mineral buildup on the heater, sump, and spray system
• Heavy daily use (multiple loads per day) shortens overall life
• Poor draining and standing water increase odor and corrosion risk
• Overloading can block the detergent dispenser and reduce cleaning performance
• Skipping filter cleaning can strain the wash pump and drain pump

Quick maintenance that extends life

These steps prevent the most common wear issues we see on dishwashers like the 804621670A.

• Clean the filter regularly; replace it if damaged (dishwasher filter 5304532206)
• Run a monthly cleaning cycle to reduce film and odor (the manual’s vinegar cleaning method works well)
• Use rinse aid and the correct detergent amount for your water hardness
• Keep the drain path clear; replace a cracked or kinked hose (dishwasher drain hose 807117001)
• If drying performance drops, inspect the heater circuit and consider the frigidaire dishwasher heating element 154825001 when diagnostics point to a failed heater

What “normal” looks like over time

Dishwasher age	What’s common	What we recommend
0 to 5 years	Minor adjustments, cleaning needs	Follow the manual’s loading and care tips
6 to 10 years	More clogs, slower draining, noisier wash	Stay on top of filter and drain maintenance
10+ years	Higher chance of pump, heater, or control issues	Compare repair cost vs. replacement

Why it matters

Knowing the typical lifespan helps you decide whether to invest in parts like a drain pump, heating element, or control board, or focus on maintenance to keep the dishwasher running efficiently and quietly.

For the Ikea dishwasher model 804621670A, the manufacturer varies by production run and region; many Ikea dishwashers have been built by major appliance manufacturers such as Whirlpool or Electrolux/Frigidaire. The most reliable way to confirm who built your exact unit is to match the model and ID details shown in the 804621670A owner's manual.

How to identify the actual manufacturer on your unit

Use these quick checks on the dishwasher itself (not the cabinet door panel):

• Look for the rating plate (usually on the tub frame near the door opening).
• Record the full model number and serial number exactly as shown.
• Compare the control layout and cycle names to the 804621670A owner's manual.
• If you are ordering parts, match by model number first, then by part ID.
• If the dishwasher has draining or washing issues, confirm the symptom before choosing a pump or control.

What we can confirm from the parts used on this model

The parts catalog for model 804621670A includes components commonly associated with the Electrolux/Frigidaire-style platform (for example, drain pump and heating element designs). That points to an Electrolux/Frigidaire-built design for many units sold under this Ikea model number.

What you check	What it tells you	Why it helps
Rating plate model/serial	Exact production identity	Prevents ordering the wrong part
Drain and wash system parts	Platform family clues	Helps narrow likely manufacturer
Control panel labeling	Series match	Confirms you are using the right instructions

Why it matters

Knowing who built the dishwasher helps you choose the correct repair approach and the correct replacement parts (pump, heater, control). For example, a no-drain complaint often leads to checking the drain pump a A00126401 and the drain path before replacing anything.

On the Ikea dishwasher model 804621670A, code 40 (often shown as i40) indicates a drainage restriction, most commonly a clogged filter that is preventing water from moving out of the tub normally. Cleaning the filter and checking for blockages usually clears the code; see the 804621670A owner's manual for the exact filter access and cleaning steps.

What to do first (quick fix checklist)

• Turn the dishwasher off, then cancel/drain if your model allows it.
• Remove and rinse the filter; scrub off grease and debris.
• Check the sump area under the filter for glass, labels, or food.
• Inspect the drain hose for kinks or a clog; replace if damaged.
• Run a short rinse cycle to confirm the dishwasher drains.

If the filter is worn, cracked, or will not seat correctly after cleaning, replacing it can restore normal draining; the correct part for this model is the dishwasher filter 5304532206.

If code 40 comes back: common causes and likely fixes

What you notice	Most likely cause	What we recommend
Water left in bottom after cycle	Filter or sump blockage	Clean filter and sump; re-test
Humming but no drain	Drain pump jammed or failed	Check for debris; consider drain pump replacement
Slow drain, occasional code	Partially restricted drain hose	Clear/replace hose; verify high loop/air gap setup
Drains sometimes, not always	Intermittent pump or control issue	Check wiring connections; test components

For a no-drain condition tied to this error, the drain pump is a common repair item; for this model, that is the drain pump a A00126401.

Why it matters

A clogged filter or restricted drain path can leave dirty water in the tub, reduce cleaning performance, and trigger repeated error codes. Keeping the filter clean also helps protect the pump and motor assembly from debris damage.
