Bosch Dishwasher E:10, heater reading in the drying container

What E:10 means

E:10 is a drying-system code. During its self-check the control read the heater tucked inside the zeolite container and got a resistance outside the normal range. That heater is part of the container, and Bosch says it cannot be bought on its own. The documented repair is therefore either the wiring that feeds it or the whole container as one assembly. Wash results usually stay normal while drying slips.

Common causes of E:10

Heater inside the zeolite container open-circuit
Supply leads at the container connector worn or loose
Drying fan blocked, so the container runs hotter than designed

✓ One safe check you can try

1. Leave the machine closed; no part of this circuit is safe for a homeowner to test. 2. Think back over recent weeks and decide whether drying faded slowly or quit all at once. 3. Mention that when you call. A slow fade tends to mean a tiring heater, while a sudden stop points toward wiring that has come loose.

! Why to stop there

The heater cannot be bought separately, so a wrong diagnosis can mean buying a full container.
Testing the container involves live connections near hot parts.
Wiring is far cheaper to fix than the container, which makes ruling it out first worth the diagnostic time.

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:10E:10 questions

How much does the container cost compared with the wiring?

The container is the larger repair, which is why we check the wiring first. We give you a written price for whichever job the testing supports, before any part is ordered.

Is the dishwasher dangerous with E:10 stored?

Not in itself. The control has flagged a heater reading, not a leak or a shock risk. Still, avoid repeated cycles with drying if you smell anything hot or see scorch marks.

Will it dry better if I use more rinse aid?

Rinse aid helps water sheet off dishes, so it never hurts, but it does not replace the heater. If the container cannot heat, drying will stay weak whatever you add.
