What the E22 Error Means
The E22 error code indicates that the filter system is clogged or that water is not draining away from the sump correctly. The sump is the reservoir at the bottom of the tub from which the circulation and drain pumps draw water. If the filters are heavily soiled or the sump is blocked, the pump cannot function properly and the machine will stop.
Common Reasons This Error Appears
Blocked or dirty filters
The most common cause — the filter assembly at the bottom of the tub has become clogged with food debris, grease and residue, restricting water flow through the sump.
Residual water in the sump
If water is not draining fully after a cycle, the remaining water in the sump can trigger this error on the next cycle.
Blocked pump inlet
Debris may have accumulated around the pump inlet beneath the filters, preventing water from flowing through the system.
Faulty circulation or drain pump
If either pump is not operating correctly, water may not circulate or drain as expected, leading to a build-up in the sump.
Safe Checks You Can Try
Clean the filters thoroughly
Remove the entire filter assembly from the bottom of the dishwasher tub. Rinse the coarse filter, fine filter and mesh filter under running water, using a soft brush to remove any stubborn grease or food deposits. Refit securely when clean.
Check for standing water
If there is water sitting in the bottom of the tub, scoop it out with a cup and check the filters and pump inlet for any obvious blockages.
Check the pump inlet
With the filters removed, inspect the area around the pump inlet for any debris such as glass, labels or food particles.
Restart the dishwasher
After cleaning, turn the appliance off at the mains for a few minutes before restarting to clear the error.
