Code

  • E33
  • E34

Cause

Inconsistency with the dry boil protection.

If your AEG washing machine displays the error code E33 or E34, this almost always indicates a problem with the pressure sensor (also known as a pressostat or level switch) or a problem with the water level..

These sensors measure how much water is in the washing machine. This is an important safety feature: the machine must know exactly when there is enough water to activate the heating element. Without this check, the machine could 'dry boil' or overflow.

What do the codes mean?

  • Error code E33: There is a signal difference (inconsistency) between the analogue pressure sensor and the dry boil protection. This means that the different sensors measuring the water level do not agree with each other.

  • Error code E34: The value of the analogue pressure sensor does not match that of the digital pressostat..

Solution

  • Inspect both pressure switches.
  • Check for current leakage from the heating element. The leakage current can disrupt the sensitive electronics of the pressure sensor, causing the machine to generate these error codes.
  • Replace the heating element, the switches, or the PCB wiring.
