Pressure switch on water pump

[Sandiegodoug]

I have an isata 3 fw, been pretty problem free other than the dripping from the auto level system which was there from day 1. A strange problem just occurred. The water pump started cycling , just barely, even though i checked all the connections, made sure all valves closed tight. It worked perfectly last dry camp, a week before. All I did was top off water. I’m suspicious maybe pressure valve dirty.
How do you access pump. Maybe i could remove check valve and clean.
Thanks

FW is under the shower, RW is in the lav base. Often times it is the Anderson valve. Either in the wrong position or an O-ring has a nick,

So take Anderson valve apart. I already upgraded to new style. How would one test to
Make sure that’s the issue?

I always start with the easy part first. Is it in the right postion? Have you cleaned the screen on the pre-filter at the pump? Start there first...

turn on hot water faucet , water heater prob. has a air bubble in it if you did not purge air a out of hot water heater tank . then purge all faucets and out side shower , low point drains ,WITH PUMP TURNED ON .

I read you checked all valves. But I had the same problem while taking rv out of storage. My outdoor shower cold water handle got moved had very small water drip in storage bay. Just enough that I could hear the pump cycling occasionally. I checked everything even low point drain valves but forgot about shower valve.

Thats why I taped those in a figure 8 to keep pressure on both handles in off direction.

Isata 3 has on-demand hot water.

Is pump and screen underneath motorhome?
I crawled under, didn’t see pump. I see a filter in bathroom, never used it.

Pump and Screen are behind a wooden panel at the front base of shower. Just take out about 4 phillips screws and you will see them both.

Thanks
I’ll take it apart when I get home

Well, I found the filter, cleaned it, and all is good again. Funny, filter wasn’t very dirty, just a bunch of white plastic shaving. Thanks everyone for assistance.
