SOLUTION
POSSIBLE CAUSE
Insufficient water in the
heating tank.
Defective timer (49).
Dump valve coil (37) is
burnt out.
Check the water level in the tank. If water is not flowing or is
flowing too slowly, check the automatic refill system (refer to
step 1 of Trouble Shooting).
The power input to the timer is at terminals 1 and 5. Voltage
between these terminals should be approximately 115 volts. If
you cannot get a reading at these terminals, check the ON/OFF
switch (30). When this switch is pressed to the ON position,
you should read approximately 115V between terminals 5B and
3A. The same voltage should show at terminals 2 and 5 of the
timer. Lack of voltage at these terminals will show that the
timer is not opening the dump valve. Replace the timer.
If the timer is working, check the coil on the dump valve. If
there is voltage, you should read approximately 115 volts be-
tween the terminals. If there is voltage, the coil may be burned.
Replace coil.
Check also for clogging or lime deposits causing the valve to
lock up. Clean or replace valve.

4. PROBLEM: Water does not pour from the sprayhead when the brew switch is pushed.
TANK LID
This brewer is equipped with a new tank lid design, part no. WC-5661. This new lid does not require
the silicone gasket that had been used in previous brewers.
1. When replacing or reinstalling this lid, make sure the tank lip is
perfectly round and free from any buildup.
2. The lid must sit in a level position.
3. Make sure that when installing the lid, the bracket or screws do not
touch the liquid level probe (see figure 4).
