Dehumidifier FAQs

The built-in pump on my TP70PWKN Dehumidifier does not auto-restart after a power failure.

The TP70PWKN Honeywell Dehumidifier with built-in drain pump will not automatically restart after a power outage to prevent leakage in case the drain tube was disconnected during power failure. The Auto Drain Pump Mode button must be manually reactivated in the event of a power outage.

My Dehumidifier continues to run even after the desired humidity level has been reached, why won’t it turn off?

There is a 5% threshold when the desired humidity setting has been reached. The compressor will shut off once the relative humidity is 5% lower than your desired setting. The fan will continue to run for up to 6 minutes to cool the motor and will then shut off. Operation restores once the relative humidity is 5% higher than your desired setting.

My TP70PWKN Dehumidifier with Drain Pump is showing an E5 Error Code – what does this mean? What do I do?

An E5 Error code suggests that there is an issue with the pump function. Check out these steps to troubleshoot before contacting the Customer Service Center:

  1. Check that the Direct Drain Cap is removed, and the Auto Drain Pump Cap and the Auto Drain Pump Tube is installed properly. If drain plug is installed, there is nowhere for water to drain out, and E5 Error code will display.
  2. Check you are using the original Honeywell Auto Drain Pump Tube and not an alternative. The Honeywell Auto Drain Pump Tube that comes with the product is engineered for the pump model to allow consistent water flow up to 5m. The diameter, lengths are determined scientifically –The error code may occur when water is not dispensing properly.
  3. Check that the Auto Drain Pump Cap is securely on the Direct Drain outlet.
  4. Make sure the Auto Drain Tube is not blocked or bent.
  5. Make sure that the filter screen on the pump is not clogged with dirt or is obstructed.
  6. Ensure that the Auto Drain Pump Cap has a washer at it’s center.
What maintenance is required?

It is recommended to clean the filter every two weeks. You can wash the filter with water, but it is important to allow the filter to dry before placing it back inside the unit. You can also use a vacuum as an alternate cleaning method for the filter. When you are finished with the dehumidifier for the season, be sure to empty any water that has been collected in the water bin. Disconnect the hose if you used one, and make sure you replace the drain cap and rubber stopper back into the drain outlet. Make sure that you store the unit in a cool place, and away from sunlight.

How is the water removed?

When the water tank reaches capacity it will cause the unit to shut off until the bin is emptied. There is also the option to attach a garden hose to redirect the drainage and allow it to run without interruption. If you choose to attach a hose, you will need to ensure that the garden hose is free of kinks and that it drains into a reliable receptor, like a sink, Please read the manual for specific instructions.

What kind of setup is required?

The portable dehumidifier is easy to setup and does not require any installation. Just remember to close all windows and doors in order for the unit to successfully work as required. It is important that it is in an enclosed area at all times while it’s operational.

What is a portable dehumidifier?

As the name suggests, a dehumidifier removes humidity. It is popular for musty basements or homes located in areas of high humidity. The portable dehumidifier sits nicely on sturdy wheels and can be easily moved from room to room. It is designed to work in temperatures between 41°F (5°C) and 89°F (32°C).

What added benefits does my dehumidifier offer?

Portable dehumidifiers are easy-to-use handy devices that can be moved around from one place to the other with ease. A portable dehumidifier works to reduce and eliminate humidity from musty basements, or from any part of your home in an area with high humidity.

Does the outlet on the continuous drain fit an ordinary garden hose?

For the Honeywell TP series Dehumidifiers (TP30WKN/TP50WKN/TP70WKN/TP30AWKN/TP50AWKN/TP70AWKN)

The TP Series Dehumidifiers do come packaged with a drain tube for continuous drainage. You can attach a standard garden hose for continuous drainage but the max length is about 1 meter OR, you must have the hose positioned vertically downwards below the height of the dehumidifier. The continuous drainage feature relies on gravity to pull the water condensation through the hose and thus if it is too long and straight, the water may collect inside the hose or return to the unit. This is standard for most gravity drain dehumidifiers. You could buy the Honeywell model TP70PWK with drain pump which would allow you to extend up to 5 meters as the pump helps to push the water further.

What does the Sleep Mode on my TP Series Honeywell Dehumidifier do?

The Sleep mode on the TP Series Dehumidifiers dim the light on the control panel and mirage display for better comfort when needed. However, the light does not completely switch OFF in order to keep settings visible throughout operation.
