10. Apply the new heater gasket.
11. Take the new heater and slide it through the hole in the wash
tank and line it up so the wash tank studs fit in the holes on the
heater flange.

secure them with the ratchet and 1/2” socket.

torge the nuts holding the wires, jumpers and bus bars to 16 in-lbs.
15. Ensuring that all non-essential personnel are clear of the area,
place the drain stopper back in the wash tank and restore power
and water to the unit. Turn the unit on and allow it to fill normally.
18. Verify that there are no leaks around the heater. If there are,
attempt to tighten it down (with power secured to the unit at the
service breaker to prevent injury) as the tank will change shape
slightly as it heats up.
19. Use the amp meter to take readings off of the power lines to the
heater, verifying the amperage draw to the machine data plate.
20. Wait until the heater contactor kicks out (meaning that the tub
has reached the appropriate temperature) and allow the machine
to operate approximately ten minutes to verify that there are no
leaks and that the heater is maintaining the tank temperature.
