Determine whether this heat-pump dryer is configured to collect condensate in its removable tank or to discharge it through the optional long drain hose. Having a hose nearby is not proof that the documented alternate routing is installed.
Models covered
DV6850N DV22N680*H* family; follow the matching drain-hose installation diagram. Do not substitute a washer drain-height rule.
Stop for smoke, burning smells, abnormal heat or repeated breaker trips. Let the dryer cool before cleaning. Do not expose wiring, bypass interlocks or work on gas components. If gas is smelled, leave and call the utility or emergency services from a safe location.
Follow the drain path
Check the parts of this route that your manual permits you to access. Note where water flows and where you cannot confirm it. Do not open covers or components that require service access.
| Observed state | Interpretation / next step |
|---|---|
| Tank collection configured | Empty and refit the tank as documented. |
| Long hose configured | Compare visible routing with the exact installation diagram. |
| Warning returns despite correct routing | Stop repeated cycles and request inspection. |
Model-specific checks
Trace the intended destination
The model comes with a built-in condensate tank and supports a documented long-hose drainage arrangement. Establish which arrangement the installer selected. If it uses the tank, emptying it before or after a load is routine maintenance, not evidence of a failed pump.
Look at the accessible route
With the appliance stopped, inspect the visible long hose for crushing or a displaced end. Compare its connections and termination with the installation illustration. Do not pull a stacked machine forward or change inaccessible connections alone; ask the installer to verify them.
What an empty tank does not prove
An empty removable tank plus a full-tank warning does not identify a pump, float or control failure by itself. Record whether condensate reaches the intended drain and how soon the warning returns. Those observations help service distinguish an installation question from an internal fault without guessing a part.
What to record next
The first diagnostic decision is the configured water destination. It avoids emptying a bypassed tank repeatedly or applying a vent-clog diagnosis to a condensate-drain problem.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
