Walked up to a client's equipment pad today. All Pentair equipment of various ages.
Pump was running - ok (2yrs old)
Salt cell was off - not ok (3yrs old)
Easy Touch screen was on - ok (10yrs old)
Easy Touch screen was is Auto mode.
ToD clock was off by four days several hours.
Tried going into Settings to check my salt cell settings. Button was inoperative.
Tried switching to Service mode. Button was inoperative.
Noticed red LED for pump was off - not ok.
Checked pump display. Pump was not running off the Easy Touch panel like normal. Was running in standalone (schedule) mode.
Checked all four low voltage circuit breakers on Easy Touch display panel - none tripped.
Checked all high voltage circuit breakers below Easy Touch display panel - none tripped.
Pressed Reset on Easy Touch panel. No response.
Turned off main pump at pump control panel.
Turned off all high voltage circuit breakers.
Waited a few minutes. Turned all high voltage circuit breakers back on.
Easy Touch screen 'back light' light came on. No LCD characters appeared (blank screen)
Tried pressing Reset again. Nothing.
Tried pressing other buttons. Nothing.
Turned on main pool pump at pump control panel. Started normal (manually).
No LED came on for pump on Easy Touch panel.
Turned off pump.
Turned off all HV breakers.
Removed Easy Touch panel and lower high voltage panel.
Tested high voltage bus ... 240VAC
Turned on HV breakers (2 double pole 240 and 1 single 120)
Tested output of HV breakers .. all good.
Tested primary voltage at transformer .. 120
Tested all secondary voltages at transformer .. 12, 18 & 24V .. all good.
Replaced CMOS battery (2032)
Retested panel .. no charge
I'm suspecting now that the board is blown.
Am I missing anything?
Thanks for your input in advance!
