I have a Bosch dishwasher displaying Error code E24
Brand: BoschType of Appliance: DishwasherModel Number: SMU68M05AUWhat have you tried so far?: I have cleaned the filter and checked for blockages in the drain hose. When started it does drain so that does not seem to be the issue. It seems to be that it will not let water in.
Have you made sure that water drains into a bucket very good when the hose is disconnected from the drain?
No I have not but I can clearly hear that it is pumping out well.
the water seems to pump out relatively quickly so I do not think that is the issue
It goes to the drain trap.
No there is no water in the bottom of the dishwasher and it is definitely an E24 code as that is what is on the display and the check water light has come on.
I'll check the drain pump but from what I have read about these dishwashers that may not be the problem.
There is no removable lower panel on this unit
Hello,I am an authorized Bosch service tech and I can help you today.Just so I understand what is happening here, on your dishwasher you are getting the e24 fault in the display and The check water light is lit and the dishwasher doesn't complete a cycle. And it is completely draining but not filling with any new water, correct?
First, the e24 is a very popular error code or fault for this model machine and for Bosch dishwashers in general. It is for a communication error between the drain motor and the main control. The control is sensing that the drain motor is either not fully draining the water or not operating at all. So if you are saying that when you get the error in the display and you open the door to check , the water is completely drained then the drain pump is likely not the cause for the fault.The computer or main board in this machine has been known to give a false error. Throwing an error or fault code when the machine is running fine. And all you need to do is power off the machine at the circuit breaker or mains in your home for ten minutes to reset the board.So if you haven't done that yet I would advise doing that first.If there is still water in your dishwasher after it has shown the error code then we will need to check the drain motor and hoses for clogs and for voltage. So if you have a meter and some tools we are going to need them.Now for the water light coming on that is an easy one. If the error comes on when the dishwasher is supposed to be filling and there is no new water coming in and the drain motor is not consistently running then you will first need to make sure that the water supply to the dishwasher is on and is on all the way. if it is then we need to check the water fill hoses screens and the water valve screens for clogs. there are screens in both the water fill hoses or supply line to the dishwasher and the water valve that will prevent any sediment from getting into the water valve then into the machine. But if there is a lot of sediment it can clog the flow of water into the machine completely. Which would give you the error code.So first thing you need to do is check that the water supply is on fully. If it is then pull the machine out and check the water supply hose to the water valve and the water valve screens for clogs.If all of that is good and you cant still find the reason for the failure then I would tell you that you had a shorted control board. And to verify you would need to check power to the drain motor during a drain cycle. and if you have voltage then you are good with knowing the drain motor is good. Next check the water valve solenoid in the same way for voltage. if you have voltage to the water valve but yet the water doesn't come into the machine and the screens are good and clear then you know you have a bad valve.But if there is no voltage to either part when it is supposed to be on then the control board is bad an needs to be replaced.Please check that and get back to me here and I will help you more.Thanks.
It is draining fine. I think initially the reset of the board may have helped. It is now running through a 15 pre rinse cycle. This dishwasher has been an issue over the last few weeks. I am suspecting something to do with the filling of it. Where is the water valve screen? I have checked the one at the tap and have cleaned that.
It has come up with the code again. I have removed the side cover to see where the water inlet goes. This unit has some wiring and some sort of valve with the hose connector. Is that the inlet valve because I can't really pick it wit the side removed.
