4. Beeps are NOT heard

If beeps are not heard but associated

LED(s) turn on and off, it is possible

that the beeper circuit has failed or that

the control board has failed. Before

replacing the control board, check

for proper touchpad functioning:

a. Disconnect the power cord from the

outlet.

b. Remove connector P3 and P4 from

the microcomputer board. Using the

table in the tech sheet, measure the

resistance across the switch when the

switch button is pressed. The meter

must be connected with the proper

polarity.

• If using an analog readout: the

resistance reading should go from

infinity (open circuit) down to about

10 or 20 ohms.

• If using a digital readout: the

resistance reading should go from

infinity down to about 2 megohms

- 4 megohms. If available you

could use the “diode test” function

of a digital meter, which will give a

voltage af about 1.2 VDC during

the test.

c. If any switches fail, this test, replace

the key switch/console assembly.

d. If they test OK, replace the control

board.

5. No washer function is activated when

a particular touchpad is pressed.

If the associated LEDs do light up, it is

possible that the control board has failed.

Check touchpad functioning before replac-

ing control board.
