is there fuses on the board?
Is the 240 measured directly at board?
Can you check for power to keypad?
Use reply
Customer: replied 1 year ago.
there is a fuse. each end of fuse is 123 volts to ground. The key pad has flat 4 wire phone type of connector. Can't read voltage. The water level sensors are the same type of wires.
Expert:  Billy replied 1 year ago.
just to make sure...the wires are 123 to ground..but are they wire to wire..
Customer: replied 1 year ago.
The display has power to it because the display has "pb" displayed. However none of the buttons function. If the water senors
are bad, this would cause the circuit board to stay off. is there a way to check the sensors? When the tub was full I taped on the sensor with no effect.
I will check the wire to wire now.
Customer: replied 1 year ago.
wire to wire is 245
Expert:  Billy replied 1 year ago.
are you sure it is Pb or P6?
Pb is a power board (circuit board) communication error
P6 is a bad remote panel.
verify because the 6 and b in digital are very close

pb not 6
Expert:  Billy replied 1 year ago.

Reset a connections and inspected board. there are no burnspots and caps are not swollen . Do you think it could be water sensors? With the display saying pb, it is probably a bad board.

Is there a good place to buy circuit boards and key pads?
Expert:  Billy replied 1 year ago.
spadepot is a good resource...
shop around with circuit board number
Customer: replied 1 year ago.
Do you agree that it is defiantly a bad circuit board?
Expert:  Billy replied 1 year ago.
Pending the connections and harnesses are ok...then it would be board
Customer: replied 1 year ago.
The board has been discontinued according to the manufacture. Are there places that repair boards? If I have to get new board, do u recommend a new key pad and transformer also?
Expert:  Billy replied 1 year ago.
I steer clear of repaired boards.
You never have a warranty and never know the shelf life.
Generally whether ebay or a retrofit you can a board. As far as board, keypad and transformer....if you really like the tub and are willing to invest in it...its best to do a pak at once.
