What Replace water filter. Press OK to start means

On the Bertazzoni CM242WTXT built-in coffee machine, this message means the water softener filter is exhausted. The display asks you to replace it and press OK to start the changeover. A spent filter no longer softens the water, so scale builds faster and the flavor can suffer. Owners see the prompt after a set amount of water has passed through the cartridge.

Common causes of Replace water filter. Press OK to start

  • A softener filter that has reached the end of its life
  • Water usage that exhausted the cartridge sooner
  • A filter fitted but not accepted with OK
✓ One safe check you can try

1. Remove the old softener filter from the water tank. 2. Fit the new filter as shown in its instructions. 3. Refill the tank with fresh water and press OK to start. 4. If the message returns after replacement, call us.

! Why to stop there
  • A used-up filter allows scale into the machine, which creates descaling work.
  • A prompt that stays after a correct changeover needs the machine checked.
  • We give a written price first, and our work has a 30-day workmanship warranty.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Replace water filter. Press OK to startReplace water filter. Press OK to start questions
Why must I press OK after fitting the filter?

The OK press tells the machine a fresh filter is in, so it resets its count and runs a short rinse. Without it, the old count keeps triggering the message.

Can I keep brewing without replacing the filter?

You can for a short time, but the water is no longer being softened. Scale then builds faster, and descaling will be needed more often.

Will an air bubble affect the new filter?

It can. A bubble in the circuit with a filter fitted may give slow or missing coffee flow. Running the rinse after the changeover usually pushes the air out.
