A Candy Smart Pro tumble dryer that turns but produces no heat may have an open heating circuit, but the heater is not automatically at fault. Begin with the programme, lint filter, condenser and airflow before checking the heater assembly, thermal devices and wiring with the appliance disconnected. The observed procedure includes removal of the rear cover, extraction of the heating element, work around a damaged area, reconnection, reassembly and restart.
The exact product reference cannot be read and the available evidence contains no electrical or temperature measurements. This guide therefore separates direct observations from professional diagnostic guidance. It does not invent a resistance value or claim that heating is correct merely because the display lights and a programme begins.
Quick diagnosis before disassembly
Empty the water container, clean the lint filter and condenser as required by the manual, and select a programme that requests heat. Restricted airflow can extend the cycle, create overheating and operate a thermal protection. If the drum turns with reasonable airflow but the air remains cold, the heating circuit becomes a credible suspect.
| Symptom | Priority check | Decision |
|---|---|---|
| Drum does not turn | Supply, door and controls | Do not begin with the heater. |
| Drum turns with cold air | Programme, airflow and heater | Test the circuit with power removed. |
| Heat stops quickly | Filter, condenser and fan | Investigate airflow-related overheating. |
| Breaker trips | Insulation, wiring and moisture | Do not retry; use a competent technician. |
| Burning smell or dark marks | Terminals, insulators and coil | Keep the dryer out of service. |
What the procedure actually establishes
Observed actions
- The front-loading dryer is inspected and moved for rear access.
- A large curved metal cover is unscrewed.
- The multi-coil heater on insulating supports is removed.
- Pliers are used around a visibly marked end of the coil.
- The assembly, thermostats and connectors are refitted.
- The display powers up and a programme starts.
Evidence limits
No multimeter, insulation tester or thermometer is visible. There is no resistance, current, outlet temperature or completed drying result. The final restart proves only that the controls allow a programme to begin. It does not prove insulation integrity, protective earth, temperature regulation or long-term durability.
Electrical and thermal safety
Remove the mains plug, keep it under your control and allow the dryer to cool. The Off button is not safe isolation. Work in a dry, well-lit area and wear suitable gloves around sheet-metal edges. Photograph every connection before removal, hold terminals rather than pulling wires, and never perform continuity testing on energised equipment.
Live testing, earth-bond verification and insulation testing require suitable equipment and competence. HSE guidance for domestic appliance servicing calls for removing the plug or fuse before repairs and performing work with equipment dead wherever possible.
Tools and replacement parts
- Correctly fitting screwdrivers;
- long-nose pliers for controlled terminal removal;
- a suitably rated multimeter used by a trained person;
- labels, photographs and a screw tray;
- an approved heater, thermostat or high-temperature terminal for the full product code;
- a vacuum and soft brush for dry lint removal.
A general-purpose connector, insulating tape, solder alone or ordinary wire is not a high-temperature repair. Record the full model and product number before ordering because Smart Pro is a product family with different constructions.
Diagnostic and replacement procedure
- Confirm the complaint. Record programme, elapsed time, drum movement, airflow and any code. Clean user-serviceable items.
- Identify the dryer. Photograph the rating plate and obtain documentation for the complete product code.
- Isolate power. Unplug, prevent reconnection and wait until every heated part is cool.
- Prepare access. Protect the floor, move the dryer without pulling its lead and take an overview photograph.
- Remove the cover. Track screw positions and support the rear metal panel while lifting it away.
- Record wiring. Photograph and label every terminal before gripping the connector for removal.
- Inspect the heater. Look for a broken coil, cracked support, browned terminal, melted point, lint or deformation.
- Test dead. Isolate a terminal where necessary and compare continuity and protective devices with manufacturer information. A dark mark alone is not an electrical test.
- Find the cause. If a thermal protection has operated, also check filter, fan and ducts. Never bypass the protection.
- Fit the correct part. Preserve specified power, geometry, connectors, insulators and thermal protection.
- Reassemble. Route harnesses away from hot and moving parts, replace grommets and refit every guard.
- Validate safely. Verify earth and insulation before a monitored functional test. Stop for smell, noise, heat or another fault.
Why a broken coil should not simply be twisted together
The coil distributes power over a designed length, cross-section and spacing. Shortening it or joining ends can concentrate heat, change resistance and stress its supports. Local manipulation is observed, but provides none of the measurements required to endorse it as a compliant repair. Replacing the exact element or complete assembly is the cautious option.
Final validation
Before reconnection
- No spare screws and every guard fitted;
- wiring clear of drum, fan and heater;
- terminals secure, clean and temperature-rated;
- filter, condenser and ducts correctly installed;
- protective earth and insulation verified.
During the test
Monitor airflow, sound, smell and abnormal stopping. An acrid smell, crackling, breaker operation or unusual casing temperature requires immediate disconnection. A completed cycle and credible drying result are required; an illuminated display alone is insufficient.
Frequently asked questions
Can a thermal cut-out be bypassed for testing?
No. It protects against dangerous temperature. Bypassing it removes a safety function.
Which heater should be purchased?
Only the part listed for the complete product code, with matching power, terminals, mounting and protective devices.

When professional help is the right choice
Stop before opening the dryer if the rating plate is unreadable, the wiring is burnt, the breaker has operated, moisture has reached electrical parts, or suitable safety-test equipment is unavailable. A competent appliance technician can identify the exact assembly, test insulation and protective earth, confirm airflow, and verify temperature regulation. This is especially important after any overheating event because replacing a heater without correcting restricted airflow can allow the same fault to return.
