Once the model and dryer type are known, match the enquiry to its moisture route. Give the programme, load and result from the last normal cycle, then add the observations relevant to that design.
Vented dryer
Describe the existing exhaust route and any visible hose crushing, disconnection or change since the appliance was moved. Mention an altered outside grille if already known. Observe only accessible parts; do not climb to an outlet or disconnect the vent to run a trial.
Conventional condenser dryer
State whether the model uses its water container or a permitted direct drain as installed. Report a tank warning, water collected and any visibly obstructed room-ventilation openings. Water in the container is an observation, not a measurement proving that the air path is clear.
Heat-pump dryer
Give the same tank or drain observations where applicable. Add which filters or owner-accessible condenser area the exact manual says to maintain, and when that care was last done. Access differs between models; do not assume an exchanger can be removed or rinsed because another dryer allowed it.
Keep the evidence safe and specific
Record approximate elapsed time and the actual damp or dry result without diagnosing a component. Follow the model's cooling and isolation instructions before permitted owner cleaning. Stop using a machine with burning smells, overheating or electrical concerns. Compressor replacement, regassing and other sealed heat-pump circuit work are outside this service.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
