hi folks
I'm in the UK,
need some advice regards overheating pump and pool filtering system all together
had this pump for around 10 yrs its a Marlow ITT J15O EC, I think its a 1hp pump, (have seen on net that you can replace with a newer model that replaces everything except the strainer bowl but can't find web page now)
this winter I fitted a 45KW heat exchanger (hot side feed from oil boiler) seemed to work ok last week under test
but this week I was vacuuming the pool as I'm just opening it, run lovely for 4 hrs then pump stopped, now pump stops every 1-2hrs,
the pump body temp is 170F when it stops so I think its overheating,
I've tried running it with vacuuming off, and skimmer and bottom drain on
with the heat exchanger on its own and with a bypass valve part open (I fitted pipework so I can bypass/isolate the heat exchanger)
pressure in my triton TR 60 filter is normal (8 psi running 14 psi needs backwash)
read pump can overheat because of, suction lines blocked, pressure lines blocked, capacitor failed (anything else ?)
Section lines appear clear, the Pump bowl it full of water,
pressure lines pressure & water in filter looks normal
capacitor I'm going to try to test today with a basic multimeter (just on ohms)
