1 year old hayward h1001d pool heater clicking

Our pool heater seems to be clicking and shaking after we turn on the heater. Checked filter and pressure - starts up fine, heats water, but clicks and shakes.....need help! Should we not run the heater while it is shaking?

Your pool chemistry is likely out of balance and leaving a residue on your heat exchanger coils. Had the same exact problem. Called a technician out and he said that I needed a new Heater after talking to Hayward. No warranty situation for sure. I went to the pool store, got 2 pieces of hose and hooked it up through my pump. Put a coil cleaner mixed with industrial vinigar and ran it for two days and all is good now. Solution after that was simply good chemistry in the pool. Salt water pool by the way.

SOURCE: 1 year old hayward h1001d pool heater clicking

Actually, the clicking is likely causing the shaking. Inside the manifold of a H100 is a stainless steel diverter plate that send some of the passing water into the heat exchanger and lets the rest past and back to the pool. When it breaks, you will hear a 'clicking' noise at it rattles in the water path. When it breaks, the flow to the heat exchanger is intermittent and you will begin to boil the water, causing the shaking. This situation is dangerous, especially without a pressure relief in the heater or pipe. As long as your water chemistry is sound, Hayward will usually cover this under warranty even if the unit is over a year old.

I have a H1001D pool heater that will not continue to stay hot. with heater turned on hi, fan comes on 20 sec.later temp. at vent is hot from the burning gas ,10 sec.later temp. is cool. fan continues...

One of the internal safeties are opening causing the main burner to shut down. Ensure you have proper water flow through the unit. It may be a high limit tripping and can be caused by several things, one being the limit is weak, second the heat exchanger may be partially plugged from scale. You may be able to determine the cause if your mechanically inclined, but I would recommend professional service.
