see this causes: Drain line/air gap drain line or air/gap clogged fix it Pump see the impeller or blade if there bent repair or replace Drain valve and/or solenoid lube the solenoid Belt worn or crack replace Motor turn on manual if doesnot the motor need replace Timer clean the contact for oxide or dirty, loose wires, break or burn repair, or REPLACE the timer. God bless you
Initially would suggest to check that the power supply requirements are satisfied. You might also need to check the breakers. Depending on the exact model number, the AC supply can be as shown below:
If the above checks out OK, then it could be as you have suspected, the controller is messed up, more specifically the firmware or related electronics. You could of course try a reset by unplugging from the mains or switching off the appropriate breakers for say half an hour.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
I am copying a solution I gave to another person about 10 minutes ago. They had a similar issue...
There is a possibility that the rotor motor which drains your water out has failed or that the propellor has worn out.
the drawer and remove the dish tray and cutlery basket. To remove tray,
it is easier to lift the back of it up first then the front so that you
clear the soap tray knob. Then remove the filter mesh which is the
disk on the bottom. To remove untwist the centre anti clock-wise half a
turn. This releases it so that you can lift it out. If you have water left on the bottom, empty out in a container with a sponge. Then you will be able to see the top of the rotor motor in the centre. Again
half a twist to free it and then lift it out. Once you remove it look
at the propellors to see if they have not chipped away. Most of the time
the rotor stops working. You can swap the rotors from the good drawer to test and see if it pumps the water out. Normally
when you start a new cycle, you will first hear the machine roof seal
motors working for a couple of seconds, then the machine goes into an
initial pump cycle for about 15 seconds. After this you will hear it
stop and then start filling up with water. Once it has filled up with
water, stop the machine and repeat a new cycle.
Pause the machine after the initial stage to see it it has pumped the water out. If the problem is the rotor you can order a replacement and fit it yourself. Very easy to do. Ash
This problem is mostly caused by the drain pump or a restricted drain line. Try taking the end of the drain hose off under the sink and re-checking the drain-out condition. If the unit is still not draining, I recommend replacing the drain pump.
Other possibilities could be that the sump is blocked, or the control or harness may need to be replaced.
Hi. The above machine stops mid cycle and drain/fill light is on, also
error code F3E, have cleaned both hot and cold water inlet filters, also
checked drain pump and drain line, all ok. Machine drains with no
issues and fills with hot water, runs for a while then shuts down.
Check the underneath the drain stem (lift up food catching screens inside the machine - drain stem will look like a long hard plastic tube) you may nee a flashligh when you tak out the tube to see the actual drain hole/ swirl your finger around the hole to make sure there are no toothpicks etc... also check on that plastic drain stem that there is a black rubber o-ring at the end of it - and is still tight.
also inside the machine there will be some plastic bubbles- (these are your float switches, which rise and shut off the fill when the water gets high enough. make sure they move either up or down (not both)
lift **** basket out and lift out samle stailees plate drain and look for stailess probe coming out of side of tank half way down there should be a white pprobably yellowed plastic ball it is a float they get old and fill fith water and don't flote telling maching I have no water keep the water coming. the float is sometimes even missing fell off andf thrown out. 10 bucks and a clip your off and running. call hobart its 110.00 and your off and running.
Favorite for bosch is the water inlet modual which monitors the water flow in could be faulty, If incorrect pulses take place the motor wont proceed. Otherwise listen for a hum after water stops filling. If there is a hum, the main wash pump is jambed and has to be sorted out.
Bosch dishwashers have a seperate pump for washing and another for draining. Try making it fill more than once. There is usually a timed fill and the float stops it before it overfills It also might prevent it from washing without enouth water Try defeating the door switch and play with the float during fill. There may be a sensor that won't let it go into wash. Be prepared to get a little wet if it should start up suddenly. A slightly safer way is to fill it with the sprayer from the sink. and see if it will go into wash.
THERE IS A FLOAT WITH A RED SHAFT /LEFT SIDE AS YOU LOOK INTO THE BOTTOM OF MACHINE. AFTER TAKING OFF KICK PLATE. IT IS GOING TO DRAIN IF THERE IS A LEAK FROM PUMP OR HOSES FILLING UP THE PLASTIC BOTTOM OG MACHINE . KEEPS A LEAK FROM GOING ONTO YOUR FLOOR.. . MY GUESS IS YOU HAVE A LEAK DOWNTHERE AND NEED SERVICE.
