Davey pump Hydrascan reset

I have a Davey XP 500 H with Hydrascan sensor. I believe it is about 6 years old.

The pump system no longer detects when the taps are operated to start the pump and supply water to the house. I know the pump works because I have tried wiring direct to the power supply and bypassed the Hydrascan controller.

I have spoken to Davey and they can only provide fault finding information for newer models of the Hydrascan; which is fitted with LED indicator and yellow reset button.

My model Hydrascan does not have the reset button; does anyone know how to replicate the reset function or suggest anything I can investigate to make the sensor operate again

Phil,
We are are davey pump dealer and see this problem every now and again where a pump won't start up all the time. With the hydrascans there is a sensor plate on the inside of the hydrascan which can be accessed by unscrewing the cap on top of the hydrascan. This plate can get muddy/dirty/grubby with age and will sense less and less as it does. To counter act this just give it a clean with a tooth brush or something that will fit in it and you should be right to go.
