Watermill pr50d pump not switching off

[Moodshadow]

Hi,

Had a Watermill PR50D installed for a while now.
Recently started to fire the pump momentarily when turning the hot tap of the bath or sink quickly - although not connected to the water feed to the pump.

This morning the wife got out the shower and the pump continued to run. Have had to turn off at the isolation switch.

Any ideas please? Is there a control board that may have failed that can be replaced or is it a new pump?

Many thanks in advance for any advice.

Pete

Hi Pete, I know it's been a while since you posted this but have found a solution? Got the same pump and having issues with it too.
