Some of the early Westy LED panels have a provision which disables the
sink pump whenever the water tank is very low or empty. You can tell if
your panel is one of these by looking at the left row of 4 LEDS. If the
2 bottom ones are red you have one of these types. On most panels this
is a green LED which indicates a lit pilot for the fridge. If you look
at the circuit board for this type of panel you will see a power
transistor that performs this function. I disable this function because
the water tank level circuit gets flaky with age and then the faucet
might not run the pump even when there is water in the tank. This
function was not important and was left off in later years. Also this
type of LED panel may have a red LED near the small toggle switch and
this LED may be used for the pilot indication. Sometimes this LED is
present but not connected as the early fridges sometimes had a small
panel meter inside the fridge to tell you when the pilot was lit. The
wire from the pilot thermocouple can be connected to either the panel
meter or the LED panel so it is hard to say which one is active in any
given Westy without tracing the wires.
