It freeze up and does not extreact water i have try new filters

if this model doesnt have the removable filter on the middle right side then the filter is not removable by std means and unit will need to be dissasembled for this , Now there are a few reasons for unit to freeze , and yes your right one of them is a dirty air filter . and if its gone too far then a dirty condenser coil as well , also if unit is over three years old then it's possible that due to overheating some of the gas chanrge has gotten out , reducing it's efficency making it run longer with no cool down and freezes up , also if your asking it to remove more water than its designed for (setting to high) it will freeze up as well , std moisture for a home is 70 %rh purchase a small meter to measure this ,(some units have one built in) see how much water you really have ?

as with any freeze up of any unit (any mfg) there are a few things to look at first before consulting a profesional ,
1st ck your filter most units have a filter these are the most forgoten things when it comes to reg cleaning , remove it and run under tap shake excess water off and replace in unit
2nd is unit warm enoght to work air temp has to excede 68 degrees for these to work
3rd how old is unit if unit is over three years and has been largely neglected for cleaning and maint issues then overheating can cause gas charge to leak out and cause freeze ups , replacement is only option on this reason
4th setting: is unit large enoght to remove water from area if its undersize it runs too hard and never cycles off/on this causes freeze ups , purchase a small humidmeter to measure the area % rh 70%rh is considered normal for a home

Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.

Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.

If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.

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

could be a couple of areas to check temperature set to low filter plugged unit low on charge fan motor needs to be replaced or fuse or breaker blown or off

If the air intake filter is dirty, that can affect the operation and cause it to freeze up. Operating in temperatures below 40 degrees will also cause it. Or a low refrigerant level can also cause it. Turn the unit OFF and unplug it. Place some old towels under the unit to absorb any dripping water. Once the unit has completely thawed, remove the filter and clean it. Carefully replace the filter (be sure it's dry) and give the unit a try.

Sounds as if the air filter may be clogged, which causes the coils to freeze. Unplug the unit and allow it to thaw. Once thawed, follow the Owners Manual"s instructions on accessing, removal and cleaning of the air filter. That should solve your problem.

Hi,
Dehumidifiers freezing up can be causes by a few different problems.

clean filter and then check the coil behind the filter to see if clean. Biggest things that freeze a unit are dirty filter or coil...or low on freon.

Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.
