How to Fix E33 Error (Step-by-Step)

Pause the current washing program and confirm the error stays cleared during a full test cycle.
Wait for a few minutes to allow the foam to dissipate on its own.
If the foam is excessive, you may need to run a rinse and spin cycle to clear it out.
Check the type and amount of detergent you are using. Ensure it is a high-efficiency (HE) detergent suitable for front-loaders.
Reduce the amount of detergent used in future washes, especially for smaller or lightly soiled loads.
Run an empty cleaning cycle with hot water to flush out any residual suds from the machine.
Resume your normal washing, being mindful of the detergent dosage.
Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
