My Dimplexcooler keeps stopping have to keep empty water every two hours

Open the RO tap and drain the RO tank (capture and use later). The tap will run a steady stream until tank empties. When tank empties the steady stream will switch to a drip, drip, drip,... This is normal and is the production output rate of the system.

If you capture the drips into a measured container a typical rate is 1 quart per hour, more or less given input line pressure and condition of system filters. Time how long it takes to capture a cup (8oz) and do the math.

The RO feed line is likely a piercing saddled type valve. It will take several turns (clockwise) to close the valve. Keep turning CW until it stops. With the tank empty (tap will drip, drip, drip,...) close the filter feed line valve and the drip, drip, drip will eventually stop, indicating the system no longer has water pressure.

High humidity causes more water on cooling mode.

Is your water jacket empty? Could be something simple like that.

i have had this problem and its usually the pc board is faulty

Sounds like the water pump may be faulty. That would keep it from pumping the water out, which might keep it spinning in an attempt to empty the drum of water.

Water pumps are generally accessible from the rear, via an access panel. Check it for debris or a worn bearing. It should be obvious.

fills up with water every 2 hours empty water back on

High humidity - keep doors and windows closed as much as possible to eliminate introducing humidity.

yes the bottom filter can be removed and washed out with warm water, this is the same problem we had

check the drain pump it may be blocked or faulty

The easiest way to empty these brewers is to turn them upside down over the sink. Turn it on it's side, always keeping the fill hole down toward the sink, and keep on going until you have the unit completely upside down. If there is a push switch under the lid to stop water from going into the pot until the lid is closed, you will have to keep this pushed in until the unit is empty
