What E07 means on this model

The fan in the Zeolite drying chamber has failed, and on a machine that uses that chamber for drying it is a real loss of function rather than a cosmetic fault. Only models with a Crystal Dry or Zeolite chamber report this code at all.

Symptoms you will notice

Code appears on a model with a heat dry or auto open function
Dishes come out wet at the end of a dry cycle
Condensation on the inside of the door panel after a cycle
The auto open feature does not open the door

Common causes

The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:

Heat dry fan motor failed or its blade fouled
Water or detergent has drawn the fan into the duct and jammed it
Fan connector or harness fault
Control board output failed

What you can safely check

These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.

Open the door at the end of a dry cycle and listen for the fan running before the cycle ends.
Unplug the machine and check that the fan duct is not packed with debris or a wet filter element.
Check the filter is seated correctly, because a filter sitting proud of its housing can touch the fan.

Do not do these

×Do not pour water into the fan duct to clear it, which is one of the ways this fault is caused in the first place.

When to call a technician

Book a technician, do not keep resetting it

This fault will not clear on its own. Every power cycle gives the control one more failed attempt, and repeated attempts are what turn a cheap part replacement into a seized or contaminated system.

If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.

Duct cleaning is a reasonable owner task. A failed fan motor is a technician repair.

What it costs to fix

Parts

Heat dry fan $50 to $130. Duct and grille $30 to $90.

Labor

One to two hours.
