When a fan blade becomes damaged or broken, it can prevent the dehumidifier from working properly and thus reducing its ability to collect water.Inspecting the fan blades is a simple process. Simply remove the filter if you detect any broken or bent blades, this could be the cause of your issue and will need to be replaced.

Fan motor is damage:

When the fan motor of your Dimplex dehumidifier is damaged, it won’t be able to collect water as efficiently as it should. This is because the fan motor is responsible for spinning the fan blades that draw in air and circulate it around the unit to help absorb moisture from the atmosphere. When this part becomes damaged or malfunctions, your dehumidifier will either not turn on, or it won’t be able to collect water properly.

To determine if the fan motor is the issue, you should first check for any obvious signs of damage such as broken or bent blades. If there are no visible signs of damage and your dehumidifier still isn’t collecting water, you may need to replace the fan motor. This is usually a fairly straightforward process, but it’s best to consult your dehumidifier’s manual or speak with a qualified technician if you’re unsure about how to do it.

Suspected compressor dysfunction:

When the compressor of your Dimplex dehumidifier is suspected to be malfunctioning, it may not start collecting water as expected. This can be due to a few different issues, such as a lack of power reaching the motor or blocked air filters which restrict airflow and prevents the motor from functioning properly.

Compressor not working

Another cause could be that the compressor has simply worn out over time, or that it’s been damaged through excessive use. In either case, a qualified technician should be able to inspect and repair the compressor if needed.

Compressor replacement is necessary:

When the compressor of your Dimplex dehumidifier is not working as it should, this can be a sign that you need to replace it. There are several reasons why this might happen. Firstly, if the compressor has worn out over time due to excessive use, then it will need to be replaced in order for your dehumidifier to start collecting water again.

Additionally, if the compressor has been damaged by something such as a power surge or overloading, then it will need to be replaced immediately in order to get your dehumidifier back up and running.

Water bucket is not place properly:

When the water bucket isn’t placed properly in your Dimplex dehumidifier, it won’t start collecting water. This is because the water bucket needs to be securely connected and sealed for the dehumidifier to operate correctly. If there’s any gap or leak between the water bucket and the machine, then this will prevent it from working properly.

The best way to resolve this issue is to double check that the water bucket has been correctly placed. Make sure that it’s firmly connected and sealed with no gaps or leaks. If you detect any issues, then you should remove the bucket and reattach it properly.

The room humidity already quite low:

Sometimes, when the humidity in a room is already quite low, your Dimplex dehumidifier may not start collecting water. This can happen for several reasons. One of the most common causes is that the room humidity is too low for your dehumidifier to sense.

The unit has a humidity sensor which triggers it to start working when the relative humidity in a room reaches a certain level. If the sensed humidity in your room is already below this threshold, then your dehumidifier won’t be able to detect it and won’t start collecting water.

The water bucket is full:

When the water bucket in your Dimplex dehumidifier is full, it won’t start collecting water. This is because the machine has a built-in safety feature which prevents it from operating when there’s too much water in the bucket. The idea behind this is to prevent any possible damage to the unit due to excessive moisture levels.

The best way to solve this problem is to empty the water bucket regularly. This way, you can ensure that your Dimplex dehumidifier has enough room to start collecting water again. You should also make sure that there are no obstructions blocking the condensation drain pipe, as this can cause your unit to fill up even faster.

And finally, if you have an auto-restart or auto-shutoff feature on your dehumidifier, you should make sure that it’s set to the correct mode for your environment. This will help keep the water bucket from overflowing and prevent any further issues.

How to reset the Dimplex dehumidifier?

If your Dimplex dehumidifier isn’t collecting water, it may be necessary to reset the unit. This can help clear out any faults that may be preventing the machine from working properly. To reset your dehumidifier, you should have to follow these steps:
