Bosch dishwasher error E18

What causes E18

Not enough water is entering: closed valve, kinked hose or low pressure.

What to do

Open the supply valve fully and straighten the inlet hose.

Can I fix it myself?

Often, yes. Try the check below first — it costs nothing and frequently clears the code.

If the code comes back

Book a visit and add the code to the booking. A technician arrives knowing which parts to bring, diagnoses the dishwasher for a flat $89 and gives you an exact quote before doing any work.
