please advise.
Expert:  Billy replied 2 months ago.

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?

Customer: replied 2 months ago.
No I don't. Can you advise please?
Expert:  Billy replied 2 months ago.

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?

Customer: replied 2 months ago.

Expert:  Billy replied 2 months ago.

thank you! now this unit uses an electronic limit...first thing - have you turned power for at least one minute?

Customer: replied 2 months ago.
Several times. Breaker has been turned off for anywhere from 10 mins to a day.
Expert:  Billy replied 2 months ago.

when you turn on does the pump start running so there is water flow?

Can you remove the filter for a cycle ?

Customer: replied 2 months ago.
No. When I turn the breaker back on all that I get is the flashing "Power" light. No water flow.
Customer: replied 2 months ago.
Which filter is it that you want me to remove?
Expert:  Billy replied 2 months ago.

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?
