Re: What are symptoms of the B II pump starting to fail?

I think you had the same symptoms I see, but a different cause.
I opened the Brewtus. No visible kinks in tubes coming out of OPV. Just to 
be sure, I rerouted those tubes so they were clear of wires. 
My brew pressure with a blank portafilter in is 9.8. I can't adjust it. The 
screw in the OPV is frozen.
I checked all electrical connections.

I brewed a shot and the pressure oscillated.

I then went and did the flow test in the video you sent.
With a blank portafilter, the flow starts and then stops. Just like in 
video.
But, the flow does not start up again. Different than video.

I suspect that either the tube is clogged and I can't see it. Or, the pump 
is starting to fail.
I did order a new pump assembly a few days ago on general principals.
When I receive it, I will call WLL and check the symptoms with them.

Re: BII - replaced PStat - what to replace next?

Thanks,
Where are the overtemp cutoff switches? I should look at them.

I had bought a pack of 100 vac relief o-rings from Amazon that are supposed 
to be good at 400 degrees.
I replaced 1.
I recently replaced the pressure stat.
I had rebuilt my brew head earlier this year with a kit of springs & seals 
from WLL. Did not solve the reason I did that. Instead I found a loose wire 
going into the PID that was the problem .
I have checked the brew leverl seal.
My PID screen is starting to lose segments from first digit. Not a big 
problem.

I ordered a new pump assembly kit a few days ago. Brew pressure during 
shots is oscillating. Goes up to 9 and then down to 5 and then back to 9. I 
suspect the pump is starting to fail.
