Kitchen tap trouble

Hi all,
Hopefully someone can help me here.
I have a 97 Euro Mobile and last weekend out of the blue the kitchen sink tap stopped working, the bathroom tap works fine and you can hear the surflo pump cut in when you open the tap on the bathroom but not when you turn on the tap in the kitchen.
I have checked and can confirm the taps don’t work with microswitches.
I removed the kitchen sink tap and there was water there and if I open the tap water poured out...I checked the tap itself wasn’t blocked and it isn’t.

Has anyone come across anything like this or any suggestions please.

He said it doesn’t operate by micro switches though

In my van, the pump has a flow switch built in. There are no micro switches or solenoid. I presume his is the same as mine. I can’t understand why one tap is working and the other isn’t though. Definitely sounds like a micro switch issue. Strange one

that could be a blockage in the line that is stopping the full flow in order to start the pump. can you disconnect the line from sink to pump and blow it out ? from the sink side, gave someone look at what comes out .

Thanks again for your input everyone.

I was able to find the line from the tap and made sure it was clear all the way back to the pump. What I did find today was, the main water pipe come from the pump and to a dividing rail, this rail seems to feed all the water pipes to the bathroom, kitchen etc. I swapped over the kitchen line and the bathroom line so the bathroom line was essentially working on the kitchen line back to the pump and that worked fine and the kitchen tap still isn’t working off the bathroom line. So I have narrowed down the issue from this dividing pipe to the tap of the kitchen.

I have double and triple checked for a micro switch under the kitchen tap and can’t see one or wires. The tap isn’t blocked but is it possible it needs to be replaced? I am stumped

Possibly a bit of limescale has worked its way into the manifold and blocked the outlet for the kitchen sink.

Might sound a bit mad, but with the bathroom and kitchen disconnected at the manifold, if you blow into each pipe with the taps open, can you blow through both?

I cleared a blocked windscreen washer nozzle pipe by taking the nozzles off and blowing into them till bubbles came up in the reservoir. Post smart comments below please ...
