Product is about 6 years old. Used in basement. Worked great until this year. Now will run continuously but collect little water. What type of service do I need? This is a 65 pint per day Whirlpool.

I second this advice!
The Continuous Run mode is really for severe humidity conditions and does not work well in moderate humidity.

There is some service that you can do ... Clean the filter and the cooling coils, regularly. Check the humidity level that you have the unit set on. It may be set to low and there's just not that much humidity in the air at this time, for it to collect. From what you said, it sounds like you may have it set on continuous cycle which could account for the lack of a lot of water in the bucket. In continuous run, the fan stays ON all the time. It's supposed to do that, so that the air is constantly moving and the sensor only turns the compressor ON, if it senses a humidity level 5% higher than what you have it set for. Try running the unit on a 1 or 2 hour cycle (if your model will do that) rather than continuous cycle.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
