Troubleshooting: Filling, Heating, and Brewing
Overfilling
watertank even
when power is off.
Fill valve not sealing
properly.
Fill valve installed
backwards.
Water entering tank
continuously, usually
slowly.
Disassemble valve and clean out
dirt. Valve may need new plunger
if seal is worn.
Problem Possible Cause Service Check Remedy
Filling Problems
The filling system consists of the following components:
• Liquid Level Control, located behind the brewer front panel.
• Liquid Level Probes, located on the tank top, secured by wing nut, under the top cover
• Fill Valve, located behind the front panel.
P200/RAPS200 Brewers
Tank does not refill.
No power at
equipment.
No water at
equipment.
Water strainer
clogged.
No power to level
control.
Level control faulty.
Electrodes faulty.
Fill valve faulty.
Overfilling
watertank only
when power is on.
High electrode coated
with lime or faulty.
Missing or faulty
connection of C
terminal on level
control to metal
enclosure.
Fill valve connected to
heat terminal on level
control.
Liquid level control is
faulty.
Jumper HI terminal on
level control to metal
enclosure stops fill.
Jumper from C
terminal to metal body
stops fill.
Check connections.
Jumper from HI to C
or metal enclosure
does not stop fill.
Remove electrode assembly and
clean both probes. If this does not
work, replace assembly.
Make secure connection of C to
metal body.
Connect black lead for valve to
FILL on level control.
Replace level control.
Nothing operates.
Crack water inlet
fitting.
Water pressure
before strainer but
not after.
Tank fills only when
probe wire is
disconnected from HI
terminal on level
control.
120V is across FILL
and N on level
control, but no fill.
Check main switch or circuit
breaker, brewer's circuit breaker or
power switch if provided.
Make sure all water supply line
valves are open.
Remove and clean or replace
strainer's mesh.
If no voltage, check for loose or
broken wires.
If no 120V at FILL terminal, replace
level control.
Replace electrodes. If no remedy,
check for improper wiring or level
probe tip touching metal.
Disassemble valve and clean or
replace plunger if frozen. If plunger
is OK, coil may need replacement.
If arrow on valve is pointing toward
water inlet, remove valve and install
correctly.
Look for direction of
arrow on valve body.
Check for 120V AC
across H and N
terminals on level
control
Disconnect probe
wire to HI terminal on
level control. Check
for 120V at FILL
terminal.
