Home Fault Codes

Bosch dishwasher codes

A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. Bosch shows the code with a leading E and a number on both dishwashers and washers.

Models covered: SHPM65Z55N, SHE53T55UC, SHX53TL5UC, SHEM63W55N.

About Bosch codes

Bosch (part of BSH Home Appliances) uses E-numbered codes on dishwashers and washers. Its dishwashers share control platforms with Thermador and Gaggenau, so the same fault can appear on those brands. The codes apply to model numbers such as SHPM65Z55N, SHE53T55UC and WAT28400UC; check the label on your unit to confirm yours.
