JennAir Flush-Mount Code E:13: Incoming water too hot

What E:13 means

The JennAir flush-mount dishwasher for European cabinets, for example the JDB9600AW, uses E:13 as a protective message. The machine runs without its heater because the water temperature went above 75 C (167 F). This is not a defect in the appliance. The thing to check is the temperature of the water supply coming to the dishwasher. The code appears in the service program list rather than on the regular customer display.

Common causes of E:13

Water supply feeding the dishwasher hotter than 75 C (167 F)
Water heater set too high or a mixing valve not working
Hot water line running very hot because of a recirculation loop

✓ One safe check you can try

1. Run the kitchen hot tap for a minute and carefully check how hot the water is; use a thermometer if you have one. 2. If it is very hot, lower the water heater setting a little. 3. Let the supply cool, then run a short program. 4. If the water is not unusually hot and E:13 still appears, call us.

! Why to stop there

Adjusting a gas or electric water heater is a separate job from dishwasher repair and can be unsafe without training.
Scalding water at the tap is a burn risk for the household.
Replacing dishwasher parts will not help when the supply temperature is the cause.
We check the supply temperature first and tell you honestly if no dishwasher repair is needed.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E:13E:13 questions

Is E:13 a sign something is broken?

No. This message is a protective reaction to hot supply water, not a defect. Once the supply is back in a normal range, the heater path works again.

What temperature triggers it?

The limit is above 75 C, which is 167 F. Most household water heaters are set well below that, so a very hot supply usually means a high setting or a mixing valve that is not doing its job.

Should I still call you?

If lowering the supply does not stop the message, yes. We then check whether the sensing side is misreading, give a written price first, and stand behind our work with a 30-day warranty.
