Siemens Washing Machine: not heating
What is this symptom?
Is your Siemens washing machine not heating water during cycles? If your clothes remain cold and error codes like E05 or E19 appear, it might be due to a faulty heating element, a malfunctioning temperature sensor, or loose wiring. Understanding these issues can help you identify the problem and seek the right solution.
Important Tips for Siemens Models
- Siemens displays specific heating circuit faults such as E05 (heating circuit fault) and E19 (heating time exceeded) which typically indicate heater or heating circuit issues.
Possible Causes
Faulty heating element
How to Identify: Water stays cold on hot wash cycles; multimeter test shows no continuity; potential error codes (e.g., E05, E19 related to heating circuit fault on Siemens displays. (TechFaultFix
Part: Heating element
NTC temperature sensor or thermostat malfunction
How to Identify: Incorrect temperature readings, inconsistent heat, multimeter tests out of expected resistance range; may trigger heating faults. (TechFaultFix
Part: Temperature sensor / thermostat
Loose or burnt wiring at heater terminals
How to Identify: Visible burnt connectors or loose wiring near the heater assembly; intermittent heating behavior. (TechFaultFix
Part: Internal wiring
Faulty control board heater relay
How to Identify: No power to heating element despite intact element and correct sensor readings; heater doesn’t activate. (TechFaultFix
Part: Control board (heater relay)
DIY Solutions
Check wash cycle settings
- Verify selected cycle supports heated wash
- Ensure temperature setting is set for warm/hot rather than cold
Inspect wiring and heating element continuity
- Unplug machine and remove appropriate access panel
- Locate heating element terminals and temperature sensor connections
- Visually inspect for burnt or loose wires
- Measure resistance across heating element; open circuit indicates failure
Next step
Choose the next step for not heating
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Heating Element
Heats the water or air inside the appliance to the required temperature.
- Typical part-only price
- $40 - $95
- DIY difficulty
- Medium
- Estimated time
- 30-45 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Temperature Sensor
Monitors the internal temperature to ensure correct operation and prevent overheating.
Thermostat
Regulates temperature by turning the heating or cooling system on or off.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Model-compatible Washing Machine parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.

Optional routine care
Maintenance supplies
These products support cleaning or routine upkeep. They are separate from the possible repair components above and are not claimed to fix this error code or symptom.
Washing Machine Cleaner Tablets
Routine tub-cleaning supplies for residue and odor control. They do not repair a mechanical, drainage, or electronic fault.
Braided Washer Inlet Hoses
A maintenance replacement option for visibly worn external fill hoses. Verify thread size, length, and hot/cold connection requirements.
Washer Drain Hose Holder
Helps secure an external drain hose at the standpipe. It does not correct an internal pump or control fault.

When to Call a Professional
Preventive Maintenance
-
Run periodic descaling or maintenance cycles: Limescale buildup on heating element and sensors, prolonging heater life
Frequency: every 3–6 months -
Check and clean inlet filters: Water flow issues that can stress heating circuit
Frequency: every 3 months

Common Issues Reported by Users
- Faulty heating element
- Defective temperature sensor (thermistor)
- Malfunctioning control board
User Suggested Solutions
-
Test and replace the heating element. Unplug the machine, access the heating element by removing the back panel, use a multimeter to check continuity. If faulty, replace with a new element.
-
Check and replace the temperature sensor. Unplug the machine, locate the thermistor, test its resistance with a multimeter. If it’s out of range, replace it.
-
Inspect and repair the control board. Unplug the machine, remove the control board, check for burnt components or loose connections. Repair or replace as necessary.
