Hayward Heatpump - E1 error - high gas pressure protection

[thejeff]

Hi guys,

My heat pump decided to not run this morning. Got an E1 fault on the screen, which my manual says is High Gas Pressure Protection in the fault list. Anybody know what this means or what could be causing it? Heat pump is a Hayward HP65B (65,000 BTU) with vertical fan.

Thanks

Jeff

Mine ended up going away on its on after being powered off for a bit. Never happened again that I noticed. Sorry can’t be any more help.
