POSSIBLE CAUSES
REMEDY
“F1 Service needed,”
“No water in Booster”
1. Low or no water pressure.
2. Faulty inlet valve or fill relay.
3. Contactor to booster heater not turning off.
4. Faulty temperature input (P12) on IO
module.
5. Faulty temperature probe (T3).
6. Faulty float switch allows heaters to
operate with no water in tub.
1. Verify incoming water pressure is 8–12 PSI.
2. Verify that fill relay is supplying voltage to fill solenoid.
Replace faulty component.
3. Check for welded contacts. Verify that output from IO
module turns off when above the set temperature.
4. Substitute a 1.2 kΩ resistor for T3, and verify that booster
heater turns off. If not, replace IO module.
5. Verify that the booster-probe resistance is correct with
respect to temperature. (See Table 1.) If not, replace T3.
6. Replace float switch.
“F2 Service needed,”
“Check booster
thermostat”
1. Contactor to booster heater not turning off.
2. Faulty temperature input (P12) on IO module.
3. Faulty temperature probe (T3).
1. Check for welded contacts. Verify that output from IO
module turns off when above the set temperature.
2. Substitute a 1.2 kΩ resistor for T3, and verify that booster
heater turns off. If not, replace IO module.
3. Verify that the booster probe resistance is correct with
respect to temperature. (See Table 1.) If not, replace T3.
“F3 No water in wash
tank,” “Check inlet
water and door”
1. Malfunction of fill solenoid or fill relay.
2. Door is open, which inhibits fill mode.
3. Faulty door switch.
1. Replace faulty component.
2. Close door to activate door switch.
3. Replace or adjust door switch.
"F4 Service needed,"
"Check incoming
power"
1. Incoming power not properly connected.
2. L3 is missing (3-phase units only).
1. Check connections to heater.
2. Verify that L3 is present and connected properly.
“F5 Service needed,”
“Check booster thermo-
stat and high limit”
1. Faulty temperature input (P12) on IO
module.
2. Faulty temperature probe (T3).
3. Faulty high-limit switch.
4. Faulty booster heater.
5. Booster-heater contactor not energizing.
1. Substitute a 1.8 kΩ resistor for T3, and verify that booster
heater turns on. If not, replace IO module.
2. Verify that T3 resistance is consistent with Table 1. If not,
replace T3.
3. Replace high-limit switch.
4. Check booster heater for proper resistance. Replace if
incorrect.
5. Verify that drive voltage to contactor coil is present
during a call for heat and that contactor closes. If voltage is
present, replace contactor. If voltage is not present, check
wiring.
