Ikea 804655850A dishwasher Parts

Most Ikea dishwashers, including model 804655850A, last 10 to 15 years with normal household use and basic maintenance (cleaning the filter, using the right cycle, and keeping water temperature and pressure in range). Ikea also provides a 5-year guarantee from the original purchase date for many models.

What affects lifespan the most

• Water quality and hardness: hard water speeds up mineral buildup on the heater and inside the tub.
• Water temperature: best cleaning performance is around 120°F (49°C).
• Water pressure: typical operating range is 20 to 120 psi.
• Loading habits: avoid nesting and keep items from blocking spray arm rotation.
• Maintenance: routine cleaning reduces strain on the pump, motor, and drain system.

Quick maintenance checklist (helps you reach the full lifespan)

• Clean the filter regularly; a clogged filter reduces wash performance and can lead to drain issues (see dishwasher filter 5304532206).
• Run a cleaning cycle for film and lime buildup using white vinegar when you notice spots or cloudy glassware.
• Use fresh detergent and make sure large items do not block the detergent dispenser from opening.
• Confirm your hot water supply is delivering about 120°F at the sink before starting a cycle.
• If the unit drains into a disposer, make sure the disposer is empty before running the dishwasher.

Lifespan expectations by component

Component	Typical service life	What you notice when it is failing
Pump and motor	8 to 12 years	Poor wash pressure, loud grinding, intermittent washing
Drain pump	7 to 10 years	Standing water, slow drain, humming without draining
Heating element	8 to 12 years	Poor drying, cooler wash water, longer cycles
Water inlet valve	6 to 10 years	Not filling, weak fill, fill errors

If you are seeing drain problems, the most common repair parts for this model include the drain pump a A00126401 and the dishwasher drain hose 807117001.

Why it matters

A dishwasher that is maintained and supplied with proper water temperature and pressure cleans better, dries better, and puts less wear on high-cost parts like the pump and motor assembly and electronic control board. For model-specific operating and care details, follow the 804655850A owner's manual.

On an Ikea dishwasher like model 804655850A, code 40 (often shown as i40) indicates a drain or filter restriction, most commonly a clogged dishwasher filter that is preventing proper water flow and draining. Confirm the exact display wording and reset steps in the 804655850A owner's manual.

What to do first (quick fix checklist)

• Turn the dishwasher off, then cancel/drain the cycle if your control panel allows it.
• Remove and clean the filter area; rinse debris off with hot water.
• Check the sump area for broken glass, labels, or food scraps.
• Inspect the drain path for kinks or clogs in the dishwasher drain hose 807117001.
• Run a short rinse cycle to confirm it drains normally.

If code 40 comes back

A repeat i40/40 code usually means the restriction is still present or the dishwasher cannot pump water out.

Common causes to check:

• Filter not seated correctly after cleaning
• Drain hose kinked, crushed, or blocked
• Garbage disposer inlet plug not removed (new disposer installs)
• Drain pump impeller jammed or weak (consider the drain pump a A00126401)

Symptoms and likely causes

What you notice	Most likely cause	What to check
Water left in bottom after cycle	Clogged filter or drain path	Filter, sump, hose routing
Humming but no draining	Pump jam or obstruction	Pump area, debris in sump
Drains slowly	Partial blockage	Hose, air gap/high loop, disposer port

Why it matters

A clogged filter or restricted drain can leave dirty water in the tub, reduce cleaning performance, and trigger repeat error codes. Clearing the restriction restores normal wash pressure and proper draining.

On the Ikea dishwasher model 804655850A, the filter area is in the bottom of the tub; the glass trap and filter assembly sits in the center under the lower spray arm. You access it from inside the dishwasher by removing the lower rack and lifting out the spray arm and glass trap assembly (see the 804655850A owner's manual).

How to find and access the filter area

1. Turn the dishwasher off.
2. Pull out the lower rack.
3. Look at the center of the tub floor; the lower spray arm sits above the filter area.
4. Remove the lower spray arm and lift out the glass trap assembly.

Most customers describe it as being under the large circular grate or assembly in the center of the dishwasher bottom.

Quick checklist before you start

• Let the unit cool if it just ran; the heating element area can be hot.
• Remove any standing water with a cup or towel if needed.
• Keep a small container nearby to empty debris from the glass trap.
• Avoid dropping screws or utensils into the sump area.

Cleaning the glass trap (center of the filter)

The manual describes a glass trap located in the center of the filter that catches broken glass and other hard debris.

• Grasp the glass trap handle.
• Rotate it about a quarter turn (the manual indicates a 90° clockwise turn) while pressing down at the center.
• Lift the spray arm and glass trap assembly up and out.
• Tip it over a container and tap out debris.

What you should see (typical layout)

Location in tub	What it does	What to check
Center bottom (under lower spray arm)	Filter area and glass trap collect debris	Clear out glass, bones, pits, labels
Left front corner	Overfill protector (float) helps prevent overfilling	Moves up and down freely

Why it matters

A clogged filter or glass trap restricts water flow through the spray arms, which leads to poor cleaning, grit on dishes, and sometimes draining issues. Keeping the center filter area clear helps the pump move water and soil out efficiently.
