I have a nearly year-old B2 with a vibe pump. Recently, the pump
has intermittently cut in and out, cycling between about 6 and 10 bar
pressure according to the gauge. This back and forth seems to be a few
seconds at each pressure. It's been going on about 30% of the time for
the last few weeks.
Any ideas on whether this is a pump issue or a controller issue
would be appreciated.
I had a similar issue last year. I started by cleaning inside the top of the "E61" head (removing the large chrome nut, and cleaning the stuff inside, etc.). I then cleaned the OPV. I eventually replaced it (OPV) even though it was spotless. Neither of these helped. In my case, it came down to diassembly of the vibe pump and cleaning. I know this is not recommended, but it looked like a very simple mechanism to me. What I discovered was bits of thread sealant had come off and were plugging up the small openings at the outlet end (if my memory is correct). Since then, no problems. Along with the OPV I ordered a Vibe pump, which eventually came, but I have not replaced it yet.

It can't reasonably be a controller issue. The pump runs when the lever is lifted and the controller has no way to stop it. The controller can cause the pump to want to fill the steam boiler instead but I'd guess you know what that sounds like.

Hoping for some insight before I call WLL. I have experienced this problem since I've owned my machine: I run water out for an Americano, or tea, etc. and every now an again the machine will read E1. Usually I turn it off OR run water through the group and things return to normal. The other day I pulled some water and the same thing happened. This time the problem has not resolved. I am left with a pump that runs constantly (never shuts off). I've replaced the pump (since I had a new one sitting in a box). I've disassembled large top nut on the group, the OPV, etc. All of those areas checked out fine. The pump runs water out of the group head if I open the lever while the pump is running, though the flow rate does not seem normal. Water runs out of the flexible line connecting the boilers (when I disconnected it to check this). The red light indicating a request for heat does not turn on. I'm no expert, but I have learned to service the machine in the past. My thought is that there is an electronic issue with the controller, or a sensor is not functioning. The switch under the water tank works fine. I actually had some luck last night with what I thought was a fix. I took off the cover, disconnected the flexible hose just past the OPV to see if water was running. Everything was fine. I did reset the High Limit button. When I reconnected it and then turned the machine on again, it heated up normally and ran fine. I was able to clean the machine with the blind PF and Cafiza. So it ran fine for that sequence. Then this morning, I turned it on and the pump began to run constantly. I've had the machine apart several times since I've owned it, and that is more than a little disappointing. Any suggestions are appreciated. Michael _________________________________________________________________ New Windows 7: Find the right PC for you.

I've been having a similar problem. No E1 errors, but a short while after being turned on, the pump starts running continuously. Did you manage to solve your issue?
Thanks, Bruce
