The unit has an open limit switch.
One of the sensors picked up a high temp fault and has remained open.
Do you know how to troubleshoot the sensor with a meter?
The easiest way is for you to take a good picture of the circuit board and post here and I can draw check points on what/where to check.
I cannot make out the board model number...could you get that for me please?
thank you! now this unit uses an electronic limit...first thing - have you turned power for at least one minute?
when you turn on does the pump start running so there is water flow?
Can you remove the filter for a cycle ?
I think our problem is the pump failed...water stalled in heater and tripped limit.
But without water flow we are going no where...can you use the meter to see if the pump motor is getting power or is hot?
