Help - Samsung dishwasher not heating the water
Hoping someone can help with my Samsung dishwasher (DW60A6092FW) — the water stays cold so nothing gets cleaned properly. Would really appreciate any advice before I fork out for a callout.
Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Samsung DW60A6092FW dishwasher washes with cold water
- The problem
- The Samsung DW60A6092FW dishwasher fills and washes but the water remains cold, so cleaning performance is poor.
- Likely cause
- The accepted diagnosis points to a fault in the heating circuit. Possible causes mentioned were the heater, wiring/connectors, control board, or a safety condition preventing heating. Poor filling or weak circulation were also noted as possible reasons a dishwasher may not heat properly, but no specific failed part was confirmed.
- What fixed it
- The recommended action was to confirm whether the machine heats at all on a hot programme, then check basic causes such as clean filters, free-moving spray arms, fully open water supply, and strong wash circulation. If the symptom remains, inspect the heater area underneath for loose or burnt wiring, damaged plugs, or signs of leaks. Further electrical checks to the heater or temperature sensor were suggested only if competent; no completed repair was confirmed in the discussion.
- Checks to try
- Run a hot programme and check after 15–20 minutes for steam or a warm inner door
- Check filters are clean
- Check spray arms turn freely and holes are clear
- Check the incoming water tap is fully on
- Listen for strong wash action rather than only filling and draining
- Inspect for loose or burnt wiring/connectors
- Inspect for signs of water leaks onto electrical parts
- Inspect for damaged plugs around the sump/heater area
- Parts or tools mentioned
- heater
- wiring/connectors
- control board
- temperature sensor / thermistor
- meter
Safety: Isolate the dishwasher from the mains before checking anything internal. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If the dishwasher is filling and washing but the water stays cold, the fault is usually in the heating circuit rather than the water supply itself. On this model that could be the heater, wiring, control board, or a safety condition stopping heat from being switched on.
Before checking anything internal, isolate the dishwasher from the mains.
1. Confirm the symptom properly Run a hot programme and carefully open it after 15–20 minutes. If there is steam and the inner door feels warm, it is heating at least a bit. If completely cold, that points more strongly to a heating fault.
2. Check for poor filling or circulation Dishwashers often won’t heat properly if the water level is too low or the wash pump is not circulating correctly. Make sure: - filters are clean - spray arms turn freely and holes are clear - the incoming water tap is fully on - you can hear strong wash action, not just filling and draining
3. Inspect the heater circuit On many Samsung dishwashers the heater is part of the circulation/heater assembly underneath. Check for: - loose or burnt wiring/connectors - signs of water leaks onto electrical parts - damaged plugs around the sump/heater area
4. Thermistor / temperature sensing If the temperature sensor reads incorrectly, the machine may never energise the heater. This normally needs meter testing and comparing readings.
5. Control fault If heater and wiring are sound, the control board or heater relay may not be powering the heater.
If you have a meter and want to go further, the heater continuity and insulation can be checked, but if you are not confident with live or internal electrical testing, it’s best left to a qualified appliance engineer. Any mains or sealed component work should be done professionally.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
