Sporadic water pressure

2015 Phaeton 40OH, Aqua hot model. Having issues with water pump. After more diagnosis I have about 15 seconds of water then it stops. It will recharge and run about 15 seconds again but will not run continuously. I removed the filter, no change. Pump seems to run fine.

With pump on and faucet open, does the pump turn off for the 15 sec of mo pressure? If so your pressure switch maybe set wrong or failed.

Pump has pressure and is not running, turn on faucet, runs good flow 15 seconds. Flow stops, shut off faucet pump runs for a bit and builds pressure again and shuts off

From what I can make out of your description, it sounds like the water pressure has to get very low before the pump will turn on, which is a pressure switch problem. I would back the pressure switch screw out (count the turns) and back in a few times while the pump is running to see if the turn on pressure changes. A rebuild kit may be in order, or a switch if that can be changed separately.

Does the cold water do the same thing?
