Bosch Washer Error Code E13: Meaning and Fix
Reading the washer display
On a washer the code appears on the digital display or as a pattern of flashing cycle lights. Note it exactly, including any dashes or sub-codes, then unplug the washer for five minutes and run a short drain cycle to see whether it returns. Bosch shows the code with a leading E and a number on both dishwashers and washers.
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.
What causes E13
- A burned-out heating element or open thermal fuse
- Heater coating of limescale reducing its output
- A faulty temperature sensor (NTC) reporting the wrong reading to the control
- A damaged wire, connector or relay on the control board feeding the heater
How to fix it
- Switch the appliance off at the breaker and let it cool completely before working on it.
- Inspect the heater wiring and connectors for scorching, looseness or corrosion and reseat them.
- Run a hot cleaning cycle with washer cleaner to cut scale.
- Test the heating element and the temperature sensor for continuity/resistance with a multimeter against the values in your service sheet.
- Replace whichever component fails the test; never bypass a thermal fuse.
- Reassemble, restore power and run a hot cycle, checking that the water or air reaches temperature in a normal time.

Questions
What does error E13 mean on a Bosch washer?
The wash heater did not warm the water as expected, or the control cannot confirm the heater is working. Exact behavior can vary by model and software version; confirm against your own manual.
Can I keep using my washer while E13 is showing?
You can run cold or short cycles in a pinch, but results will be poor, and a heater that stays on is a safety concern, so repair it soon.
How do I clear E13, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
