Why do dehumidifiers turn off and stop collecting water? This is something that callers ask us over and over again. I think that once someone has invested in a dehumidifier they want it to collect water on a daily basis and they are disappointed when it stops collecting water. Before I explain why the dehumidifier not collecting water is perfectly normal lets switch to another piece of equipment that we use in the house that we have a greater understanding of – our central heating.
An explanation – with the aid of the central heating example.
When we set the thermostat to say 22°C our radiators become hot, if we were to put our hands on the radiator later and found it to be lukewarm or cool then we would not think that the radiator is faulty, we would just accept that the room temperature is up to 22°C and the radiator has been turned off by the stat. We know that when the room temperature drops the radiators will turn on again and they will once more be hot to the touch.
Back to the dehumidifier and the same thing is happening, albeit in reverse. You select your set point and the dehumidifier dries the air down to this point, when the relative humidity falls below this level the dehumidifier stops working. When the relative humidity rises again the dehumidifier will turn itself on and start to collect water again.
Hopefully that makes sense and you now know why your dehumidifier sometimes stops working.

Hi, we’ve had our Meaco now for around 3 years.. we’ve moved into a new home about a month ago.. the dehmidifer was working fine up until now. For some reason it’s staying on 61 and isn’t shutting off or collecting water.
6 month old Meaco DD8L… using proper silicon hose to drain external, last few weeks it is draining to tank despite external hose fitted.. filling up and switching off.
Cut back hose 30mm and refitted. Had meacos for last 7 yrs always with same setup, never had issues before.
