Plumbed in Vesuvius - water not stopping

Recommended Posts

Had the Vesuvius plumbed in via a Flojet for a few months and has been running fine. When the water drops to minimum, pump kicks in and fills to between a third and half way then switches off. The switch underneath is lit (on)

However recently, at the point the pump previously switched off, it continues to pump, but in small pulses about half second apart. Only stops when I turn pump of of turn off stop valve. I switched out the Flojet to my brand new back up and same thing. I’m sure the pump is not the issue. The stainless braided hose looks ok although it may have a slight pinch at one point. Not sure what the issue might be or if anyone can point me in the right direction.

Running it from the tank at the moment which works as it should.

It is not unknown for 'pinched' pipes to be damaged inside. Depending on how badly it was pinched initially, it can break/ tear the inner lining leaving a flap that acts as a ' flap valve', intermittently stopping and starting the flow.   Just a possibility.

I think I've a spare hose from my L1. Just got to check connections to see  if it will fit.

1. The pump starting and stopping is the flowjet?

2. When it's starting and stopping, have you checked the inlet pipe in the Vesuvius tank to see if water is coming into the tank, just take the black lid of ant watch it as the flowejet? pulses

3. do you have an accumulator or check valve in the flowjet line?

1. Yes, the Flojet - Vesuvius runs fine from the tank.

2. I watched it whilst holding the black lid. When it was working it would have a continuous pump sound until it reached just over a third full then stop. Now it pumps via pulses of 2 per second and water enters the water tank and continues until it overflows. Fills slowly but doesn’t stop. 

3. Have a Shurflo accumulator between the Flojet and V . There is a John Guest stop valve on the pipe from Shurflo to V

From what you say it's probably some debris or lime scale in the inlet solenoid valve seat. Dismantle valve and clean.

Will do, thanks.

Approached the inlet solenoid from bottom of machine. Removed the  infeed  pipe, then removed the nut that this attached to. Not sure if there was anymore to remove as it was the main unit then. Cleaned it then put back together.

Same issue with the pump pulsing. It still pumps / pulses when the green lighted switch is turned off.

Maybe a complete removal and strip down is required. Would I need to remove the top and side cases as access from below appears tricky to completely remove.

When I had to get the boiler plate off, I took all bottom and sides off and top tilted on a towel and sorted it out. It's ok if you have all the right tools.

As Jony said, each side panel can be removed individually. However it's the actual solenoid valve you need to clean.

 

You can do a quick check, just put a blanking nut on the output of the machines pipe (fed by the flojet and if it stops) pumping and if before water was filling the Vesuvius tank when it was pulsing, then it's definitely solenoid out and give it a good clean. You have to take the solenoid apart and clean the rubber flap bit inside. It's simple to do. The hardest bit is getting the solenoid out of the machine, the rest is easy.

It sounds like you only cleaned the feed pipe and outlet? If so, that won't do anything to solve the problem.

Thought that was the case. When I cleaned the one on my L1 it was a complete disassembly required. Its only when you start to take it apart you appreciate how solidly it's put together.
