SOURCE: Pump stopped working

replace the cartridge

Posted on Aug 15, 2010

SOURCE: Laing model 330 Pump not working-delay in hot

Question not 100% clear.

1) The pump is not working? Does the pump make a noise? if pump is not working full-time, it can cause delay in arrival.
If pump motor is suspect, and outlet has power, then check override switch located on timer. Set override to Timer, move some of the trippers outward, then manually rotate timer dial until pump turns ON.
http://waterheatertimer.org/images/IMG_9325-grundfos-timer-800.jpg
If no noise is detected, or noise stops and starts, or seems strained, or if pump is hot, then pump motor may have burned out.

2) If pump is working, and makes noise like a humming sound, and pump motor is not hot, but hot water is not circulating, then unplug pump so it will not overheat and burn up.
Disassemble the pump and cross-over piece. Clean piping with white vinegar or CLR. Do not soak in CLR or it will damage seals. Rinse parts thoroughly. Reassemble and see if problem is resolved.
If pump is vibrating, then suspects include sediment and/or air inside line, and this can be resolved by cleaning as described. Also install air vent to increase life of pump.

3) Other causes for hot water delay at faucet are crossover.
Crossover can be caused by bad single-handled faucet cartridge, and/or by clogged-or-failed check valve on cross-over piece on grundfos.
This type of problem lets cold water enter hot line, and causes delay in arrival of hot water. Clean-or-replace the grundfos cross-over piece, and replace bad faucet cartridge.

Where can I get the wiring diagram for the Laing Autocirc? I want to wire in a momentary switch so that when I am ready to get in the shower I hit the switch and the pump runs until the water is warm and...


If you have the same Autocirc product I have, then it cannot be taken apart. The timer seems to be connected and sealed together with the pump. If yours is different, answer back with the wires that you can see and we'll see if the timer can be by-passed.

With the ordinary Grunfos-type pump that is not on a timer, you can add a switch and have the pump work on demand as you describe.

And they make a product that does the specific job you describe. It's called a Demand Pump. Link above shows two different types at page bottom.

I have not tested either Demand Pump shown. They operate on-demand ... when you activate the pump, the pump quickly brings water over from the hot water heater.

So the Demand Pump has a higher volume pump than the Autocirc or Grunfos.

I question a two things about the Demand Pump. 1) How will the increased pump pressure affect local pipes, especially supply tubes under a sink. 2) How HOT does the pump get? If pump gets hot, and it is located under bathroom sink next to paper goods, then that is a hazard. Some regional building codes don't allow ceiling light bulbs in closets because the bulbs get hot and start fires when people pack their closets full.

if you had a "pop" and lightning from the timer....
the water got into the electronics.
its time to replace.
getting hot.... was the cartridge either spinning dry, or spinning but not able to move water, did you have a valve off somewhere?
you might call laing or one of their distributors and see if its under warrantee.
where are you located, I can probably help you find a distributor.
