In one paragraph
No heat on an Equator unit narrows quickly. Either the heating element or its relay has failed, a thermistor is reporting a temperature the water never reached, or the machine is being fed cold water on a cycle too short to heat it.
Symptoms, including the ones that mean something else
- Crockery is cold at the end of a full cycle — Open the door immediately at the end: no steam and cool plates is the clearest sign.
- The cycle runs much longer than it used to, then finishes cold — The board is waiting for a temperature it never sees, and eventually gives up.
- An error indicator at the end of a cycle that otherwise completed — Some platforms flag a heating timeout rather than stopping the wash.
- Plastics come out wet but china is dry — That is residual-heat drying working normally, not a heating fault.
- NEAR MISS: only the top rack comes out poorly done — Uneven results with normal heat is a spray or loading fault.
The ranking that matters
- Heating element or its relay has failed — The leading cause here: the element sits in the sump, it cycles every wash, and when it opens the machine carries on washing cold rather than stopping.
- Fed from a cold supply with a short cycle selected — Next in order: worth ruling out early because it is free to test and because it is a setup fault rather than a failure.
- Thermistor or thermostat reporting the wrong temperature — Less often, third: a sensor that reads high tells the board the target is met, so the element is never asked to work and nothing appears broken.
Where to start, and what follows
- Confirm the symptom precisely before anything else — A full hot cycle that ends cold, with no steam and an undissolved tablet, is the evidence a technician needs to go straight to the element circuit.
- Run the longest hot cycle the machine offers, empty — If the door is hot to the touch at the end, the heating circuit works and the fault was the cycle.
- Note whether the cycle time changed as well as the temperature — A sensor reading high usually shortens the heat phase; an open element lengthens it.
What you can safely check yourself
- Open the door the moment the cycle ends and look for steam — Steam is the cheapest temperature gauge you own.
About 5 min
- Check the dispenser for undissolved detergent — A whole tablet at the end is strong evidence of a cold wash.
About 5 min
- Clean the filter, sump and both spray arms — Removes the water-flow explanation before the temperature one is tested.
Tools: gloves, soft brushAbout 20 min
- Check which supply the machine is plumbed to, if the connection is visible — Cold-fed machines need the long cycle to reach temperature.
Tools: torchAbout 10 min
- STOP HERE before testing the element or the relay — Element and relay checks mean a meter on mains terminals in a wet sump.
Power, water and what comes first
Safety
Power off at the breaker before any panel comes off. Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. allowlist:unplug-before-service
When this becomes a service call
An owner can eliminate soil, spray and cycle choice. Proving which part of the heat circuit is at fault needs a meter on mains terminals in a wet cabinet, so that part is a technician job.
