Hello everyone!
I have the following problem: We have a cistern with an external pump located in the heating cellar, and this pump is acting up. Sometimes it works, sometimes it doesn’t.
When it runs, it runs perfectly, with enough pressure and everything fine. But when you try to start it the next day, it makes NO sound at all. Turning the power off and on again doesn’t help, and the cistern is definitely not empty.
I’m somewhat handy, as people say, but so far I have no experience with pump technology or anything similar, since we only recently bought the house. Therefore, I would appreciate any tips or ideas for troubleshooting that can be offered through “remote diagnosis,” which might save me from having to replace the pump.
It is a:
Grundfos Hydrojet 4651 BAAE with a
Condor MDR21-EA automatic switch
Manufactured in 1995
If more information is needed, I will try to respond as quickly as possible :-)
Many thanks in advance!
Best regards, Sebastian

Hi,
I’m also just an amateur in this area.
To me, it sounds like a loose connection or possibly a damaged spot in the cable. Both ends still have contact, but it can be interrupted by movement or similar actions (for example, by shaking when turning off the pump). Then the contact is lost and the pump does not run.
This is all explained in very simple terms and hopefully understandable. On the other hand, this is probably the first thing you checked.
An empty cistern should not affect whether the pump runs. In that case, the pump would simply “run dry,” but in my opinion the pump motor would still be running.

That is also my assumption; it is usually the first thought when something works intermittently. It could have been that these types of pumps have a common “classic” problem with exactly this error pattern. Basically, a tip indicating that the issue is usually found at point XY, for example, the pressure sensor in the switch or something similar.

A dry cistern should not affect the pump operation. He does have an automatic switch, but people might understand that differently. For me, it would be a dry-run protection. So it could also be that this automatic function is "malfunctioning."

He does have an automatic switch, but underneath that, you could interpret all kinds of things. .I'll call it that for now, although there is probably a more precise term that I'm not familiar with. The switch is installed upstream of the pump and is located together with the pressure gauge on the pressure tank. Since the switch has two positions (Auto + Off), I assume there is a pressure sensor or a diaphragm inside that controls the power supply to the actual pump.
