Dishwasher displays E13; water may be excessively hot or cycle stops unexpectedly.

Safety first: Disconnect power and allow the dishwasher to cool if it has overheated.

E13 is associated with excessively high water temperature.

• Step 1 – Check water connection:
  • Verify whether the dishwasher is connected to cold or hot water.
  • If connected to hot, ensure the temperature is below the maximum specified by Siemens (typically 60°C).
  • Consider reconnecting to a cold supply if local hot water is very hot.
• Step 2 – Sensor check:
  • Inspect the NTC sensor and wiring as for E02/E11.
  • A faulty NTC reading low resistance can cause the control to think water is hotter than it is.
• Step 3 – Control/relay check:
  • If water is clearly overheating during the cycle, the heater relay on the control board may be stuck on.
  • This requires control board replacement.

Do not continue using the dishwasher if it overheats; this can damage plastic components and pose a safety risk.
