Hello,
I have a Hayward H300FDN that is failing to go into start mode.
The unit worked last week and got the pool up to temp. I saw that it was leaking from the heat exchanger a bit and ordered a replacement exchanger. I let the heater run for a few days with the dripping while waiting for the part. A few days in the heater stopped igniting. It did not even attempt start and no error code. If I set it to heat the blower does not come on. I could hear relays on the control board going through a clicking pattern, It ran through the pattern a few times and would switch to the off mode but the clicking pattern continued even when off.
The heat exchanger arrived today and was installed. Everything is back together. I verified all connections are made and water is flowing through the heater.
The heater is acting the same. The blower does no start but the relays are clicking. This is a fairly new unit. The heat exchanger required replacement because I let the PH get out of hand last year.
Does anyone have thought on what to check?
Thank you!
