Question about Hayward 116k HeatPro Heat Pump HP3100

1 Answer

I have a EUS PE 52A-102B-5 which was installed in 1995; and it has been working perfectly without any service until last winter season. PROBLEM (after not running for Summer season as I go North); Spa heat pump starts and runs about ten seconds and stops; continues doing such as long as powered "On". Last season it did the same but I wrapped on the internal piping/valve assembly, etc. with a small hammer and it cured the problem for the whole winter season. This year I tried same with no result. By the way, when I first turned it on a couple of days ago, the cycling "off" / "on" occurred a few times and then it ran for an hour or so just fine. Any suggestions? Bob Desrosiers

SOURCE: I have a 4 year

I would suspect that the motor bearings are going bad....when starting cold they turn hard and kicks the overload....running for a few seconds provides a bit of heat and then they turn a bit easier, but they still turn hard enough that the motor will shut down after a long time... the motor will probably run longer on cooler days or when it is in the shade...

Bottom line is that the motor will need to be replaced....removing the motor from the pump can be a real bugger...and often the pump impeller is destroyed till you get it removed...causing you to need a new pump impeller anyway....

You may be better off buying a complete new unit...check it out first!

Toro leaking gas through air filter

The inlet needle in the carb is leaking, it may be the activating arm has stuck, remove the float bowl and gently work the float up and down a few times, make sure the needle is moving. Failing that replace the needle valve.

Can i know life time of panasonic 102b video camera?

The life span of a video camera is relative to how often you use it and how you use it. The camera is mostly the video head. If the video heads are kept carefully by using quality tapes by renowned manufacturers the Camcorder lasts for very long. My on experience is that if your heads are cleaned properly without stressing them then you can go on for years. i have had my camera for a long time and it seems to perform perfectly well up to now.
