Details:
PVC volumetric flow meter Impeller reel fan with 2 magnetic contacts. Typically fails if there has been a build-up of minerals such as magnesium or lime on the metal contacts. Usually, the flow meter top and O ring are replaced at the same time - see below.
You will need to replace the flow meter if:
If the volumetric panel no longer programs - (Could also be PCB failure or panel needs to be replaced )
If the volumetric button no longer works - Could also be panel needs to be replaced.
If the LED no longer lights up on the flow meter (if you have a led, some flowmeters don't have LED light ) - This means that the impeller is not making contact with metal due to mineral buildup
How to replace the flowmeter lid :
Make sure that the main water is turned off at the stopcock.
Remove existing flow meter connector wires - - pay attention to where the earth and live were.
Remove the old flowmeter top - 3 screws - a cup full of water will escape from pump pressure.
Replace with new flow wheel and replace inside gasket.
You may have to replace the flowmeter top as well - no need to replace the whole flowmeter as that can be tricky to remove.
