Error codes – Πλυντήρια πιάτων Bosch SMS Series

All codes E01, E02, E03, E04 and E05 all indicate a power module failure.

This is not a fault that can be repaired by the owner as the modules have to be configured in order to operate, please see the information notes below.

As far as we are aware many models of Bosch either are or, will be set up this way in order to eliminate the possibility of DIY or third party repairs to these appliances.

This fault code will usually do what it says and be telling you that the door switch, the one used to tell if the door is closed and the lock engaged, is faulty. However, this series of Bosch dishwashers also do get the handles broken from time to time and this could be a cause.

Essentially this error code states that the dryer fan, used for fan drying in some models, is faulty or not operating for some reason.

By heat pump we assume the water heating element as that’s al that makes sense. Assume that a new heating element will not be a cheap item to buy and they are pretty specific to production within the series and it is better to check with us for the correct element.

As above, this is most probably going to be an issue with the heating element as the thermistors have their own fault codes below.

Quite how the dishwasher senses this is not known but it would seem to indicate a poor flow of water through an instantaneous heater in the dishwasher as that would seem the only logical way in which this could be detected. This would assume that the inside of the heater was choked with limescale or, blocked in some other way, preventing the correct flow of water through the heater. A poor flow of water could cause the element to overheat and fail.

This error code can be caused by the thermistor or the wiring to it being faulty.

Seek engineer if displayed.

Generally seen if connected to a hot water supply, if not it could indicate a sensor or board failure.

Float sensor in the base has been activated. You can try to empty the base and restart the dishwasher as you will find noted many times in the forums but, if there is a leak this error code will simply be displayed again, you must find the cause of the leak.

This would indicate the lack of incoming water, which will ordinarily be caused by a water inlet valve having failed.

The dishwasher has, for some reason detected an overfill and is reporting that through this error code. The flow sensor note is there as that can cause this fault code to be displayed.

As above only in reverse, the machine has not filled with enough water and this can be caused by the water valve.

Seek engineer if displayed.

The electronic controlled has detected a short or a break in a winding in the main recirculation pump or main motor of the dishwasher.

This would be caused by a blockage or a poor water flow from the main motor of the dishwasher. This can be caused by a capacitor failure or for other reasons.

Seek engineer if displayed.

The controlled has detected a break or short in the drain pump wiring. Many of these dishwashers use this pump which is a cheap compatible one.

Clear the filters.

This can be caused by the above or by, as the fault code indicates, a blocked drain pump.

There is little details on this error code.

Seek engineer if displayed.

We would strongly advice seeking an engineer for this fault as well as it is often not easy to understand or diagnose issues with turbidity sensors.
