If your condenser or heat pump dryer's water tank isn't collecting water, it indicates that the moisture extracted from your clothes isn't being properly directed into the reservoir. This issue can stem from several common problems within the appliance's water collection system.
Understanding these potential causes can help you troubleshoot and resolve the problem, ensuring your dryer operates efficiently and your clothes come out dry.
Common Reasons Your Dryer Isn't Collecting Water
The primary reasons a dryer's water tank might not be filling include blockages within the system, malfunctions with the water pump, or issues with how components like the condenser tray are aligned or seated. Addressing these areas will often resolve the problem.
1. Blockages
Blockages are a very common culprit when a dryer's water tank isn't collecting water. Lint and debris can accumulate in various parts of the dryer's drainage system, impeding the flow of condensed water.
- Lint Filters:
- Main Lint Filter: While primarily for air circulation, an extremely clogged main lint filter can sometimes indirectly affect efficiency if the dryer isn't properly condensing moisture. Always clean this after every load.
- Secondary Lint Filter (often found near the condenser): Many condenser dryers have a secondary filter that traps finer lint before it reaches the condenser unit. If this is heavily clogged, it can restrict airflow and moisture extraction, preventing water from being condensed effectively.
- Solution: Locate and thoroughly clean this secondary filter, usually accessible behind a flap at the bottom front of the dryer.
- Condenser Unit:
- The condenser unit is where the warm, moist air is cooled, causing water vapor to condense into liquid. Over time, lint, fabric softener residue, and dust can build up on the condenser fins. This insulates the condenser, making it less efficient at extracting water.
- Solution: Remove the condenser unit (refer to your dryer's manual for specific instructions) and clean it under running water, ensuring all lint and debris are removed from between the fins. Allow it to dry completely before reinserting.

- Drainage Hoses and Channels:
- Some dryers allow you to plumb them directly into a drain, bypassing the water tank. If you're using the tank, ensure the drainage hose isn't accidentally routed to an external drain, or that the internal hose leading to the pump/tank isn't kinked or blocked.
- Internal channels that guide water from the condenser to the collection sump (where the pump is located) can also get blocked with lint and gunk.
- Solution: Inspect any visible hoses for kinks. If internal channels are suspected, a service professional might be needed for deeper cleaning.
- Pump Filter/Sump Area:
- The area where condensed water collects before being pumped to the tank (often called the sump) can also accumulate lint and debris, potentially clogging a small filter designed to protect the pump.
- Solution: If accessible, clean the sump area and any associated filters.
- The area where condensed water collects before being pumped to the tank (often called the sump) can also accumulate lint and debris, potentially clogging a small filter designed to protect the pump.
2. Pump Malfunctions
The dryer's water pump is responsible for moving the condensed water from the bottom of the dryer (the sump) up to the removable collection tank. If this pump isn't working, water won't reach the tank, even if it's condensing correctly.
- Signs of a Faulty Pump:
- No Water in Tank: This is the most obvious sign.
- Unusual Noises: You might hear grinding, humming, or no sound at all from the pump when it should be running.
- Water Leakage (Internal): Sometimes, a pump can fail in a way that causes water to collect inside the dryer's base or leak externally, rather than going to the tank.
- Causes of Pump Failure:
- Electrical Issue: The pump might not be receiving power.
- Motor Failure: The pump's motor could have burned out or seized.
- Impeller Blockage: The impeller (the part that spins to push water) could be clogged with lint or debris, preventing it from rotating.
- Solution: Check for electrical connections if you are comfortable. A clogged impeller can sometimes be cleared if the pump is accessible. However, if the motor has failed, the pump will likely need to be replaced by a qualified technician.
3. Misaligned Trays or Components
Even if the water is condensing and the pump is working, improper alignment of internal components can prevent water from reaching the collection tank.
- Condenser Tray/Housing:
- The condenser unit typically sits in a tray or housing that collects the water as it condenses. If this tray is not seated correctly or if its seals are compromised, water might bypass the collection system and accumulate in the dryer's base or evaporate.
- Solution: Ensure the condenser unit and its housing are securely and correctly inserted according to your dryer's manual. Check for any visible damage to the tray or its seals.

- Water Collection Tank (Drawer):
- The removable water tank itself must be properly inserted into its slot in the dryer. If it's not fully pushed in, or if it's seated incorrectly, the connection point for the pumped water might be misaligned, causing water to spill internally rather than fill the tank.
- Solution: Remove the water tank and reinsert it firmly, ensuring it clicks into place if applicable. Inspect the tank for cracks or damage that could cause leaks.

Troubleshooting Checklist
Before calling for service, run through this quick checklist:
Step | Action | Potential Outcome |
---|---|---|
1. Clean Filters | Thoroughly clean the main lint filter and any secondary lint filters (e.g., near the condenser). | Improves airflow and condensation efficiency. |
2. Clean Condenser | Remove and clean the condenser unit under running water. | Restores efficient moisture extraction. |
3. Check Water Tank | Ensure the water tank is fully and correctly inserted. Inspect for damage. | Confirms proper connection for water collection. |
4. Inspect Hoses | Check any visible drainage hoses for kinks or blockages. | Ensures water can flow freely from the condenser to the pump/tank. |
5. Listen for Pump | With a load running, listen for the sound of the water pump. It usually makes a gentle whirring noise. | Helps determine if the pump is attempting to operate. |
6. Program Setting | Verify the dryer is set to a program that requires water collection (e.g., sensor dry, not timed air dry). | Ensures the dryer is attempting to condense moisture. |
When to Call a Professional
If you've performed these checks and the dryer's water tank is still not collecting water, or if you suspect a deeper electrical or mechanical issue like a truly broken pump, it's best to consult a qualified appliance repair technician. Attempting repairs beyond your comfort level can lead to further damage or safety hazards.
Taking proactive steps by regularly cleaning your filters and condenser unit can significantly reduce the likelihood of encountering these issues. For more detailed maintenance tips, refer to your specific dryer's user manual.
