Is E18 on a Bosch dishwasher an emergency?

Usually not an emergency. If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

Take the photo. We’ll tell you what it is.

What E18 means

“The water level is too low, or water is not being pumped correctly.”

— Bosch Home Appliances US, Dishwasher Error Codes | Support | Bosch. Codes vary by model: check your dishwasher’s own manual.

The same code can also show as: E3200.

Where E18 fits

In plain words, E18 is about the water supply or level — too little water arrived, or the level sensor reads wrong.

Bosch gives 2 other water supply codes for this dishwasher: E14 (There is a flow meter failure or an issue with water flowing into the dishwasher or the filling system), E16 (There is an issue with water flowing into the dishwasher or the filling system).

Next to E18 in Bosch’s table: E16 (There is an issue with water flowing into the dishwasher or the filling system) and E19 (There is a detergent dispenser solenoid circuit fault/error).

What to try first

  • Check the water supply valve is fully open and the inlet hose is not kinked.

Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

How urgent is it?

At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.
