JennAir Flush-Mount Code E:02: Heater relay on the power module failed

What E:02 means

JennAir flush-mount dishwashers built for European cabinets, such as the JDB9600AW, show E:02 when the power module reports an internal problem. The working relay that switches the heater has failed, so the machine runs without heating. The customer display shows E:02. Dishes finish a program wet and not very warm, and the listed repair is replacing the power module. Nothing else about the wash itself is affected.

Common causes of E:02

Working relay for the heater on the power module defective
Power module needing replacement

✓ One safe check you can try

1. Let the circuit sit off at the breaker for about a minute before powering up. 2. Run a short program and feel the tub for warmth at the end. 3. Check that the hot tap supplying the kitchen is working. 4. If E:02 returns, stop running programs and call us. Do not open the lower panel or touch any wires.

! Why to stop there

A failed relay sits on a board that carries line voltage.
Only a test with the panel open can confirm it, which owners should not do.
Continuing to wash without heat leaves grease on dishes and glass.
We give a written price for the module before ordering it.

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:02E:02 questions

Is the heater element itself broken?

The wording points to the relay on the power module that switches the heater, not the element. The listed repair is a new power module.

Can I wash without heat?

The dishwasher still washes, but results are poorer and drying is weak. For a short time it is fine. Do not rely on it for greasy loads.

How much will it cost?

Module price depends on the part and labor. We tell you the full amount in writing before work begins, and we back the repair with a 30-day workmanship warranty.
