Question about Grundfos Hardware & Accessories

1 Answer

The Gundfos Selector valve next to the water tank is making a humming and draining noise. We have switched all heating off but it still continues. The valve and the pipes above are very hot but not the ones below. Please advise?

SOURCE: Grundfos installation with Buderus boiler. Pump

Do you have more than one zone? If so, it is difficult to tell if the circulator in question is actually running. A trick is to get a screwdriver and place the metal end on the front of the circ and the other on your ear. You will hear it if it is running. If you do hear it, is the circulator itself very hot to the touch? If it is, it may be burnt out, or the zone needs to be bled of air. Another doubtful, but possible, answer is that the circulator is installed backwards. There is an arrow on it and it should be aimed towards the flow of water.

SOURCE: my indirect heat water tank not getting hot water from the circulator pump to heat the water tank when it is called from the theromsat. Please help.

Check if you have an electric motorised valve in the pipe line. If this has failed then it would stop the hot water circulation. It should have a lever to manually open the valve as a simple check if it is working.

When hot tap is turned on there is a banking noise from boiler.Have had new pump fitted and have domestic hot water and central heating.Noise continues, but not as bad as before.When heating switches on...


try by draining tank. it may have sediment build up in it. heres how. go to www.ehow.com/how_5544402_drain-hot-water-tank.html this site will explain it better. have a good day! Sediment can drift into recirculation lines, jam open check valves, and cause the recirc pump to stick until it burns out. it causes noise, sometimes enough noise to annoy, or even frighten, people if the tank is inside a dwelling. The noise is caused by small amounts of water under the sediment layer turning to steam bubbles, which then collapse violently.

Not filling with water


Hello there and welcome to fixya
here's no water at all If there's no water at all, make these checks: Is there water getting to the machine? Is the water-volume selector switch set properly and are the control panel buttons pressed in all the way? If you have a Maytag® or a ge washer, is the fuse (if there is one) in the control panel at the lid-switch bracket blown? Is there a faint buzzing or humming noise coming from the water-inlet valve? (The water-inlet valve is the device on the washing machine that the fill hoses are attached to.) If you can't hear anything, the water-inlet valve may not be getting any power. If you can hear some noise and there's water present, you may need to completely replace the water-inlet valve.
Please keep m,e posted on what you find so i can continue to help troubleshoot
and replace any parts that you may need ok
Best regards Michael

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.
