Thermador Code E22: Dishwasher Fault

Code E22 means: Thermador dishwasher error E22 means the filter and sump area is clogged so water cannot drain or circulate properly. It falls under dishwasher fault — Dishwasher fault codes usually point to a drain, fill, or leak issue — problems that are often visible, like standing water or a blinking light, before the code ever appears.

Checking the drain filter and water supply line is safe and often resolves simple cases — beyond that, it’s worth having a technician confirm.

If it’s leaking, turn off the water supply until it’s inspected to avoid water damage; otherwise short-term use is usually fine.

Not always — it’s often a clogged filter or hose, which the diagnostic visit determines before assuming the pump has failed.

It varies by which component is involved, confirmed in writing after the on-site diagnostic.

Once diagnosed, most are same-visit repairs.
