Question about Hayward H Series
My hayward H series above ground heater. Will start up and heat for 30 seconds and then heat shuts off. Motor still runs. I bypassed the sensor on exchanger by pulling the two wires off and jumping them. heat still does not keep coming. There are three sensors and I jumped across all of them in succesion. I don't think sensors are problem. can you help. thanks jack
Sounds like the heat exchanger is sooted up. Desoot...messy job but sounds like you know your way around the heater

Tips for a great answer:
you for posting your question here on Fixya.com.
Hayward H100 has a diverter plate welded into the header that helps direct some
of the water flowing thru into the heat exchanger to heat the water. If the
weld fails the diverter can interfere with that flow and cause overheating or
poor flow thru the heater which in turn can lead to the problems you describe.
the inlet side hose once you have blocked the flow of water from the pool and
you should see the diverter in the inlet. If you can move it then it is broken
and needs to be fixed back in place or the whole heat exchanger needs to be
the diverter is not moving then your issue is likely an overall water flow one
and the next place to look is the filter. Poor overall system flow may be
enough to close the pressure switch telling the heater the pump is on but not
enough to keep the water in the exchanger from getting too hot, again causing
the symptoms you describe.
