Model WFL 2462/24 washing machine. Why isn't water heated?

Add water to increase water height, and hence increase the pressure to the pressure switch, if it's not blocked with soap debris it should tell the programmer that it has water, and allow the heater to turn on.

Try out this site. Hope this helps :)

Bosch WFF washing machine error codes:

E1 - The door is not closed and cannot therefore lock.
E2 - Washer will not fill with water.
E3 - Washing machine not heating.
E4 - Washing machine won't empty.
E5 - Fault in the motor drive circuit.
E6 - Unexpected heating.
E7 - NTC thermistor open or short circuit.

Please note that the codes for the WFF range of Bosch machines differs from other ranges.

Does the machine heat the water Is the heater open circuit.if you test the heater for about 30 ohms and no leakage to earth with a megger the its OK Next go for the NTC If you don't know what i'm talking about the you should get professional help. good luck to you Tony the washing machine man.

need to replace wash heater remove front panel heater held in with one 10 mm nut easy to fit.

Light's on mean you have power.

Initiate the self test program by doing the following -

To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on
by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press
ON/OFF button.
To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each
program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended
and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault – note circulation motor stops shortly after it started
during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain
where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150ºF) and water won’t stop
circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end
shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Let me know what you figure out. I can repair these boards most of the time.

Hi there

if element changed recently when it failed it may have damged heater relay on back of control module if the heater or this has failed you will only get a cold wash on any prog they will take nearly four hours to finish if it takes normal time to wash but doesnt heat will probably be an ntc fault this is attached to heater and easy to replace.

BAD CONTROL BOARD TO TEST TO SEE IF THIS IS THE ISSUE RUN TEST PROGRAM
To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by
pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ “20” = version 0 without jumper). When
wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and
REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display
alone). Cycle Countdown display will show "88" when REGULAR WASH button is pressed and "8h" when Delay Start
button is pressed.
To start testing, press both SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended,
Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added
together, (e.g./ “6” = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor ("Sensotronic") fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code "4" and unit will continually fill and drain where
testing won't be completed. If flow switch (e5) has failed (opened), display will show "0", water won't heat (to 150ºF) and
water won’t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code "8" immediately and
testing will end shortly after water has started circulating

Thermostat is attached to the heating element

f is fill fault to much or not enough water or water in the sump white plastic base the f code will not go away until you solve the problem when the f code shows up the drain motor will run all of the time
