What to do if Grundfos Water Pump light is on but pump doesn't run?
If the 'Pump On' light is illuminated on the PM2 of your Grundfos Water Pump, but the pump isn't running, it could be due to a defective relay contact in the PM2 or a seized pump shaft. Check the electrical supply in the pump motor terminal box. If there's no voltage between Live and Neutral terminals, the PM2 is faulty. Also, check that the pump shaft is free to rotate.
What to do if Grundfos Home Booster 3.0 runs then stops and red light is on?
If your Grundfos Water Pump runs briefly, then stops and a red light comes on, here's what you can check: * The pump may be air locked, so check that the pump is vented. * The storage tank might be empty, so check the water level in the storage tank. * Also check the incoming mains water supply and the ball valve for any debris.
How to troubleshoot no lights on Grundfos Water Pump PM2 controller?
If there are no lights on the PM2 controller of your Grundfos Water Pump, it indicates a power supply issue. First, check that the mains isolator is ON. Next, check the fuse in the plug or switched fuse isolator. Finally, confirm that there is 240V between Live and Neutral.
Why Grundfos Water Pump delivers pressure but doesn't stop?
If your Grundfos Water Pump delivers the correct pressure but doesn't stop when there's no demand, it could be due to a couple of reasons. First, the pressure setting might be too high, so check the switch settings in the PM2 controller. Second, there might be a flow demand or a leak in the system. To check this, close the outlet isolating valve; the pump should stop. If it does, a system flow is keeping the pump running on the flow switch.
Why Grundfos Home Booster 3.0 Water Pump stops and starts again?
If your Grundfos Water Pump stops and then restarts after a few seconds, the precharge pressure in the vessel might be incorrect. Check the vessel precharge pressure and adjust it to 90% of the cut-in pressure setting.
