You are close to buying a new one if it runs all day. My basement is completely underground and I kill any dehumidifier in 3 years. Only time it shuts off is in the dead of winter with temps below 20*. I've done the big box and local store brands with extended warranty, but now they are no longer repaired just replaced.( 1 time)
I suggest buying one step up for recommended square footage and how warranty issues are resolved, (in home or in shop). My latest purchase is a Soulas from Menards and it works ok for the last year and a half. They are cheap and would be money ahead to just replace it every 2 years for my situation. Ok rant off.
