Neff E22 Dishwasher Error Code — What It Means & How To Fix It

Diagnosis

What this error means

Blocked Filter System

E22 on a Neff dishwasher indicates a blocked filter. Shared with Bosch and Siemens, this is the most common dishwasher fault and is always the first thing to check. A clean filter takes less than 5 minutes and resolves the vast majority of E22 cases.

Also known as: Same as Siemens & Bosch E22

How to fix it

Time 15 - 20 Minutes

Skill Anyone

Switch off and unplug the machine

Never work on an appliance connected to the power supply.

Remove the lower basket and locate the cylindrical filter unit in the centre-bottom of the machine.

Turn the cylindrical filter anti-clockwise and lift it out. Also remove the flat mesh filter plate beneath it.

Rinse both filter components under a hot tap. Use a soft brush (an old toothbrush is ideal) to scrub away grease and trapped food particles.

For heavy limescale, soak the filter in a solution of white vinegar and warm water for 10–15 minutes.

Refit the filter, ensuring the cylindrical part clicks back into the locked position when turned clockwise.

Run a hot maintenance wash (60°C or above) with a dishwasher cleaner tablet to clear the internal pipes.

Common questions

Frequently asked questions

How often should I clean my Neff dishwasher filter?

Ideally once a month, or more frequently if you wash heavily soiled dishes without pre-rinsing.

My Neff dishwasher filter is cracked — does it need replacing?

Yes. A cracked filter will allow debris to bypass it and enter the pump. Replacement filters are inexpensive and easy to fit.

Will cleaning the filter improve my Neff dishwasher's cleaning performance even without E22 showing?

Absolutely. A partially blocked filter reduces wash performance gradually before eventually triggering E22. Regular cleaning is one of the most effective maintenance steps for any dishwasher.
