What to do when E22 shows on the home appliance

Kind of codeFilters

A filter has reached the end of its life or is clogged enough for the appliance to notice: a refrigerator water cartridge past its gallons or months, a hood's grease or charcoal filter loaded with residue, a dish-care filter packed with food, a washer inlet filter choked with grit. The fix is a clean or a new filter of the right part number, fitted with the appliance unplugged and the water closed where there is one, then the reminder reset.

Usually leads toWater filter and descaling service

Fresh filters in dispensers and ice makers, and scale cleared from steam ovens, ice makers and dish care machines.

Shows up asDishes Coming Out Gritty or Spotted: Filter, Spray Arms and Rinse Aid

Dishes coming out gritty are plates and glasses with sandy specks, dried food, a white film or spots after a full cycle, often worse on the upper rack or in one corner.

MakeThermador

A Thermador kitchen asks for upkeep in several places at once: star-shaped burner ports, steam oven scale, a column unit's coil and the hood's baffle filters.

Before you book,
in this order.

Each step comes from Thermador's own guidance for E22 on its home appliances. Follow it to the end: the last card says whether this is a visit.

01

Remove the filter from the base of the tub and wash it under running water with mild soap and a soft brush.

02

Check for trapped debris or a mesh that has come loose before refitting it.

03

If E22 returns soon after a clean, correctly seated filter, book a visit to check the wash pump.

Still there?

It usually turns into water filter and descaling service. Book with the code and the model number.

What not to do

E22 is not the wash pump itself failing; Thermador's own cause is a blocked filter, cleared by hand. A pump that will not run at all with a clean filter fitted is a separate problem.

In Thermador's own words

E22 / E-22 ... The dishwasher filter is blocked. The filter is the area where food particles get caught and it needs to be cleaned regularly.

Questions
about E22.

Can I clear E22 myself?
Remove the filter from the base of the tub and wash it under running water with mild soap and a soft brush. If it comes back, it needs a visit.
How often does a Thermador filter need cleaning?
Thermador calls for regular cleaning without a fixed number; a busy household running full loads daily benefits from checking it more often than a lighter-use kitchen.
Can a small item cause E22 even with a fairly new appliance?
Yes. A glass fragment, bone or label caught in the filter mesh can trigger it regardless of how new the unit is, so it is worth checking directly rather than assuming a part has worn out.
What if E22 keeps returning after cleaning?
Confirm the filter is fully reseated and locked; if it still returns, book a visit so the wash pump behind it can be checked.

Back to your everyday

Still showing E22?

A booking goes further when it has the reminder or code as shown, the model number from the rating plate, and a word on when that filter, screen or tub was last cleaned. With those three, the office can pack the right filter or cleaner for your appliance.
