Aquatec DDP 5800 pump - model 5853-7e12-j524
Aquatec accumulator - model act820-jg.
Pressure is very close to 0 at group head with the rubber blocker in. See the three blinking low pressure lights occasionally. Also occasionally dumps to blinking boiler light.
Things I have tried:
- Put the PSI on the accumulator bladder up to 40 psi
Removed the accumulator and ran directly from pump
Validated flow of water into jug
I tried to tighten the expansion valve to no avail.
I took apart the intake bit for the flow control and I didn't see any debris on the screen ( part 275 ).
The steam pressure looks good.
Waiting on a part to inline a pressure guage on the water source.
Looking for ideas. What's potentially keeping the pressure low?
