AEG Dishwasher i10 Error: Meaning, Causes & Safe Checks

i10 Usually simple Safe checks first

Quick answer

AEG dishwasher i10 (or i11, AL5, C1, or one beep) is a water inlet problem. Check the tap is fully open, other taps are running, and nothing else is using water at the same time. Test the flow, check the inlet hose for kinks, clean its filter, and check the drain hose. Then book AEG service.

Also shown as i11 AL5 C1

What i10 means on a AEG dishwasher

Little or no water is reaching the dishwasher (a water inlet problem).

Applies to: AEG dishwashers. Models without a display beep once or flash once.

What you might notice

Likely causes

What you can safely check yourself

Stop and call a qualified engineer if:
  • A hose is split, bulging, cracked or leaking at the connection. Stop using the appliance until the hose is replaced.
  • Water flow at the tap is too low, or the tap or valve is seized. That is a plumbing job for a plumber or your water supplier, not the appliance.
  • The code or problem comes back after you’ve done the safe checks on this page.
  • The next step would mean removing a cover or panel, or working on the pump, valves, heater, motor, door lock or wiring. That is a job for a qualified engineer.
  • The appliance is still under warranty. Contact the manufacturer first, because DIY work can affect your cover.

Work through these in order. Stop as soon as one of the signs above applies.

Make sure the water tap is fully open

  1. Find the isolation tap or valve on the pipe feeding the appliance, usually under the sink or behind the machine.
  2. Check it is turned fully on. On lever valves, “on” is usually when the lever lines up with the pipe.
  3. If other taps in the house have low pressure too, the problem may be the mains supply rather than the appliance.

Don’t force a stiff or seized valve. It can break inside without opening.

Check the water flow with a bucket test Take care

Before you start
  • Turn off the water supply tap to the appliance before disconnecting any hose.
  1. With the tap off, disconnect the inlet hose from the tap end (or use a nearby tap on the same supply).
  2. Hold the hose end in a bucket, or put the bucket under the tap, and turn the water on fully for a timed period.
  3. Compare what you collect with the figure in your manual or in the brand note below. A weak flow points to the supply, not the appliance.
  4. Reconnect the hose hand-tight and check for drips when the water is back on.

For this fault: AEG: you should be able to fill a 5-litre bucket from one tap in 30 seconds. If it takes longer, contact your water supplier. Don’t run other water-using appliances at the same time as the dishwasher.

Check the dishwasher inlet hose and filter Take care

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  • Turn off the water supply tap to the appliance before disconnecting any hose.
  • Expect water to come out. Put towels and a shallow tray or baking dish down first.
  1. Where you can see it (usually under the sink), check the inlet hose isn’t kinked, twisted or damaged.
  2. With the tap off, unscrew the hose from the tap connection and clean the small filter inside of scale and debris.
  3. Reconnect hand-tight, turn the tap back on slowly and check for drips.

If the inlet hose is damaged, leave the water off and the dishwasher unplugged. A damaged hose must be replaced.

Check the dishwasher drain hose

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  1. Where you can see it (usually under the sink), check the drain hose isn’t kinked, twisted, squashed or damaged.
  2. Check its length and the height of the drain connection against your manual. Hoses that are too long, too low or too high drain badly.

For this fault: AEG: drain connection 40 to 85 cm high, and the hose no longer than 400 cm.

Don’t pull a built-in dishwasher out of its housing. If the hose can only be reached that way, ask an installer or engineer.

Check the sink waste connection

  1. Run the sink tap. If the sink drains slowly, the household drain is blocked, not the dishwasher.
  2. Check the spigot on the sink waste where the dishwasher hose connects isn’t clogged with food debris.
  3. If the dishwasher was just installed or moved, check the blanking plug was removed from that spigot.
  4. If the hose connects to a waste disposal unit, check the plug in the disposal unit’s dishwasher inlet has been removed.

When to call an engineer

If the checks above don’t clear i10, or any of the stop signs apply, contact AEG or a qualified appliance engineer. Have the model and serial number from the rating label ready, and start with AEG UK support.

Repair or replace?

Most i10 cases are cleared by the safe checks above. If they don’t help, the remaining causes are parts an engineer has to diagnose. We don’t publish repair prices because they vary by area, part and model.
