Error message Whirlpool - Clean filter

error message "Clean filter" - despite inserting a new filter

To fix this error message, there are 4 different ways:

• Clean the new filter thoroughly once anyway
.
• In the filter line lies at most an air bubble. You can remove this with the help of a garden hose. To do this, insert the garden hose into the filter receptacles and rinse the filter line thoroughly
.
• Drill one or more small holes (approx. 3 mm) in the top of the filter cap. Here the water then flows through again and compensates for the negative pressure
.
• It is possible that the pressure switch is defective. To check this, remove the filters, switch the fuses off for 1 minute and then on again. If then still this error message appears, the pressure switch is effectively defective
