AEG dishwasher i50 error
Stop using the machine
The motor that drives water up to the spray arms is not behaving as the control board expects, so the wash is abandoned. The manufacturer publishes this as one fault covering the whole i5 range rather than giving each suffix its own meaning. Debris that slipped past the filters has reached the wash pump and is obstructing it is the most common cause.
- Difficulty
- Technician job
- Time needed
- About 35 min
- Checks
- 6 steps
The same fault is shown as i51, i52, i53, i54, i55, i56, i57, i58, i59, i5A, i5C, i5D, i5E, i5F on some AEG series, depending on the display and the model year.
Before you start
- Unplug the appliance before putting a hand near the filters or the well beneath them. Glass collects there and the pump is mains driven.
- Do not tip the machine over or take off its base panel to reach the wash pump. It sits alongside mains wiring under a tub that still holds water.
- Do not keep restarting the programme to see whether it clears. Repeatedly driving a stalled motor is how a repairable fault becomes a replacement.
What it means
The motor that drives water up to the spray arms is not behaving as the control board expects, so the wash is abandoned. The manufacturer publishes this as one fault covering the whole i5 range rather than giving each suffix its own meaning.
Most likely causes
Ordered from most to least common, with what each one looks like:
| Cause | How likely | What you would see |
|---|---|---|
| Debris that slipped past the filters has reached the wash pump and is obstructing it | high | The filters were found loose, damaged or missing when last inspected |
| Fragments of a breakage from an earlier cycle have travelled into the pump housing | medium | Something shattered inside the machine recently and the pieces were never fully accounted for |
| Scale and hardened fat have stiffened the motor after years of short, cool programmes in hard water | medium | Chalky deposits coat the tub and only quick or eco cycles are ever selected |
| The motor winding or the board output driving it has failed electrically | low | Nothing at all is audible from the pump at the point in the cycle where washing should begin |
Fix steps
Tools needed
- Gloves
- Torch
-
Take the plug out of the socket before inspecting anything, and leave it out for the whole of this check.
Expected result The appliance is dead and the motor cannot be energised while you are working.
-
Take the filters out and confirm they were correctly seated and locked, since a filter that was never engaged is the usual route for debris to reach the pump.
Expected result You establish whether solids have had a free path into the machine's working parts.
-
Wash the filters thoroughly, then search the well and the openings around it by torchlight, lifting out every fragment with gloved fingers.
Expected result Nothing solid remains anywhere you can reach.
-
Check the spray arms turn freely and that their jets are not plugged, since a stalled arm loads the pump.
Expected result Both arms sweep a full circle by hand and water would pass through every jet.
-
Lock the filters back in, reconnect the power and start a short programme, listening for the wash pump as the cycle begins.
Expected result The pump picks up smoothly, the arms turn, and the fault does not reappear. If it does not, go to step 6.
-
If it returns, arrange a service visit. The wash pump sits beneath the tub and reaching it means dismantling the appliance, which is not a job to attempt at home.
Expected result The engineer arrives knowing everything reachable has been cleared and the pump itself is the remaining suspect.
Parts needed
| Part | Part number | Typical cost |
|---|---|---|
| Wash pump motor | Varies by model | Varies by supplier |
When to call a technician
Call a qualified technician for this one. The steps above are safe to carry out yourself to confirm the fault, but the repair involves work that should not be attempted without the right training and equipment.
Common questions
What does i50 mean on a AEG dishwasher?
The motor that drives water up to the spray arms is not behaving as the control board expects, so the wash is abandoned. The manufacturer publishes this as one fault covering the whole i5 range rather than giving each suffix its own meaning. Debris that slipped past the filters has reached the wash pump and is obstructing it is the most common reason for it.
Can I keep using the dishwasher?
No. Stop using the machine until the fault is resolved, because running it in this state risks further damage or a water leak.
Is this something I can fix myself?
No. This one should go to a qualified technician. You can safely carry out the first checks below to confirm the fault, but the repair itself is not a DIY job.

Related codes on the same machines
- i10 The machine asked for water and not enough arrived, so it stopped rather than starting a wash with an empty tub.
- i20 The machine has tried to empty itself and the water has not gone, so it has stopped with dirty water still standing in the base.
- i23 The cover that seals the drain pump is loose, fitted incorrectly, or missing altogether, so the pump cannot build suction and the water stays where it is.
- i24 Something solid has reached the drain pump and is stopping the impeller turning.
- i30 The anti-flood device in the base of the machine has been triggered by water where there should not be any.
- i40 The appliance cannot get a trustworthy reading of how much water is inside it, so it halts rather than guessing and either running dry or overfilling.
