Water pump .

[T Rev]

A friend’s water pump on his Bailey MH is not working.

The tank is full but reading empty.

Would this prevent the pump from working?

The other day ours wasn't working even though I had just put water in, at least half full. The Truma display warned about using the pump with 0% tank capacity, or something similar.
It turns out I had left the drainage valve next to the heater open, from it being in storage, and the water was just p!ssing out the bottom.

No, but how do you know that the tank is full, has he just brimmed it and it is reading empty ?

Yes. He needs to recalibrate the sensor. If showing 0% water level the pump will not run.

Bailey have a strange electrical system I think it's been mentioned on other threads if the tank registers empty the pump won't run.

Yes, if it thinks the tank is empty it won’t run, to protect the pump (although it is a diaphragm pump, so can run dry)
It can be overridden by holding the pump button on the control panel in continuously for as long as you need the pump to operate.
Obviously this is not very convenient long term, but is a short term solution.

Sounds like that’s the problem.

Any ideas on how to recalibrate?

Depends on his control panel. On mine in the Water Level menu there is a place where you start with an empty tank and tell the system it is empty, then fill the tank and tell the system it is full.
I think I used the Return button ( backwards arrow) to get into the sub menu in Water Level.

How to Calibrate Bailey autograph 2017 water sensor.

Please help. We have a Bailey autograph 79-4T 2017 which is fitted with a BCA Seattle control panel V3.2.2 . We are having issues with water level sensors reading incorrect. I have fitted 3 different new sensors all showing incorrect level. I have checked the length is set in manufacture...

Maybe the sensors are scaled up and need cleaning?
