Bosch dishwasher code E18: not enough water coming in

What it means

The water level is too low, or water isn’t being pumped correctly.

What to try

Unplug the dishwasher before any step beyond a quick look, and turn the water off before touching hoses.

1. Make sure the water supply to the dishwasher is turned on.
2. Check the inlet hose isn’t kinked or damaged.
3. Bosch specifies a water flow of 10 liters (about 2.6 gallons) a minute.

On models that show E:32-00, Bosch’s manual also lists blocked filters where the supply or AquaStop hose connects. Bosch says to switch the dishwasher off and unplug it before checking them; your manual shows where they are.

Resetting a Bosch dishwasher

Once you’ve fixed the cause, Bosch’s way to cancel the cycle and clear the code is to press and hold Reset (Start on some models) for about 4 seconds. The dishwasher pumps out the water, which takes about a minute; then open the door and press On/Off. For electronic faults, Bosch’s code list says to switch the dishwasher off at its breaker for 30 seconds. If four lights flash and it beeps, Bosch says to press On/Off, switch off the power for at least 2 minutes, then switch it back on; if it happens again, press On/Off, turn off the water, unplug it and call Bosch.
