SOURCE: Zanussi DE540X Dishwasher

I have the same problem. First fault was caused by poor workmanship on the assembly of the PCB. There is a relay (the largest component on the board) which was badly soldered and caused some arcing resulting in solder splattered around the plastic casing and a lost electrical connection. This relay switches the mains voltage on to the heater i.e. 240V around 8.5A for a 2kW heater. (26 ohms suggests a 2215W heater for the case mentioned). Re-soldering this connection solved the problem for about a year. Now the dishwasher is showing the same problem. I have tested the relay and it is operational, but does not seem to be turning on during a wash cycle. A new board costs around £100. Zanussi will not even provide the technical details to allow a home fix. I will post my finding if I get to the bottom of this problem. It may be to do with electrical temperature sensor. My hunch is the controlling PCB is cheaply made and will not last a reasonable lifetime. A dishwasher is in itself a very simple piece of equipment with only a few valves, a pump and a heater so should not give problems in its first five years of life subject to normal usage. I will not consider purchasing any Zanussi appliances in the future.

SOURCE: dishwasher element and thermostat

Did anyone get this sorted, mines doing the same. It stops at position 12, no power at the heater, so it stalls. I have replaced the dual thermostats, and the heater element is returning 25ohms resistance.
Its doing my head in!

Bosch dishwasher sms 4012 stuck in the wash cycle and goes on for hours without moving forward


Check the temp of the water in the machine. It could be too low and the machine is trying to heat it and cannot. If that is the case, it is either a sensor or the heating element.

Water not heating up and not drying


Hello

If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.

Incoming Water
Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat
The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.


Heating Element/Drying Fan

The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

Additional Concerns

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

Hello Brien, First let me start by apologizing for the difficulty you've had here at FixYa. It is unfortunate the assistance (or lack of) was not helpful or specific to your inquiry, but I'd like to attempt to make amends. I am quite familiar with your model and in fact have serviced Bosch for around 15yrs. When you receive the timer (It is very rare to need one in a Bosch, more likely stat on the inside door panel) I'd be more than willing to guide you through the process and I will even send you a complimentary service manual if you provide an email address. I will understand if you have closed the door on any further input from "experts" here at FixYa but will do what I can to help if you're open. Sorry once again and good luck going forward. Regards, Macmarkus :)

Heating element replaced. Worked one load and back or dryer seemed very hot. Turned off and later ran on low. Next load no heat.


Hi.

There is either a problem with the thermostats that turn off the heating element, or the heating element is plugged (elements has contact to ground and stays always on).

Heating element and thermostats are tested reading Ohms with a multimeter set at Rx1. If the circuit is open (Ohms stay infinite), then the part is defective.

If the machine overheated, then the element may be gone again. Test reading Ohms.

Also replace the thermostats (there should be two or three of them), unless the element had a contact, the most common cause for overheating is a shorted thermostat.

Regular cycle took 3 hours then would not shut off. Stopped at 1 min. soapy water still filled the bottom, dishes had soap on them. water finally drained almost out but I am afraid too run another cycle. ...


There is a heating element in the dishwasher that heats the water to about 155F at which point a thermostat closes and sends power to the timer to advance. If the water does not reach this temp, the dishwasher will not advance. Often the problem lies in a faulty part in the heating circuit like the heating element or the thermostat faulty but you will need a technician to verify.
