4.1.11 Water inlet valve
Dishwashers use standard horizontal coil water inlet valves.
Dishwashers UC/43 and later have valves with (Rast 5)
connectors. The valve nestles in the left side of the base and is
held into place with two screws.
•
When reconnecting the water supply to the water valve,
don’t overtighten the elbow fitting. On valves with vertical
solenoids, the plastic can crack and cause leaking if
excessive force is used.
•
Using Teflon tape on water fittings can help prevent
leaking.
•
The water valve can be accessed without removing outer
door or base cover. However, removing them will provide
easier access.
4.1.12 On/off switch
The on/off switch turns the dishwasher on
and off and is crucial in resetting controls.
Contacts 5 & 6 reset the control. Whenever
a control won’t reset or won’t go into wash
programs, check the on/off switch and
jumper. Replace switch and jumper if
they’re faulty.
4.1.13 Door latch
Other than occasional misalignment, the
only door latch repairs will be replacing
microswitches. Door latches are held in
place in console (frames) by tabs. It’s
important latches are properly seated in
consoles and tabs are fully inserted into
latches.
4.1.14 Terminal block
Terminal blocks (UC/40 and later) clearly show line (
L
), neutral
(
N
) & ground (
G
) connections. Dishwasher wire harnesses have
spade terminals which connect to terminals on the rear of the
terminal block.
Terminal blocks can’t be installed in the field – the terminal box
assy with terminal block must be ordered. The terminal box assy
assures the terminal block is properly grounded to the terminal
box.
