Burstner Delphin 625 06 model. Odd tap behaviour (4 Viewers)

[AlyandRob]

Folks, does anyone have any ideas/ suggestions?

We’ve just taken ownership of a Delphin Performance 625, registered in 06.
It needs some TLC (we knew this when we took it on).
The water works fine in the kitchen and the shower, but the bathroom tap will only run if the kitchen tap is on. As soon as we turn off the kitchen tap the water stops running.
I’m thinking there’s a valve or a water pressure issue.
We’ve filled, cleaned and run the tank through a few times now as well as removed and cleaned the taps.

Any suggestions on where we should start?

Sounds like your water pump is operated via a micro switch on each of your taps, and the bathroom tap micro switch has failed or the wiring to it has a problem.
By turning on the kitchen tap, it allows the pump to run which is then pumping water to your open bathroom tap.

mitzimad, I think that you have a Burstner Delphin ?

As above, broken wire for the micro switch which activates the pump. Its a beggar to get at as you have to undo the big nut underneath the sink, disconnect the two pipes (there's a little red clip fitted between the pipes that you have to remove first [long nose pliers] that allows you to pull the pipes out of the tap body. You'll probably see the two wires coming out of the bottom of the tap, but they generally break up inside due to flexing when you operate the tap lever.
Sometimes it's the microswitch itself that's failed, still a pain to access, but a cheap enough part.
