It's sound to me the problem with compressor! to make sure yourself please do the following. Press recover & fix a vacuum gauge on machin Compressor suction port(without connect to vehical) & monito the gauge is going to13"HG suction,if not then you need to replace the compressor. you can also check spin-on filter (press MENU button on the scree & then keep pressing up or down arrow key till appear "FILTER CAPACITY", then press ENTER key). if the filter already recover 68KG/150LBS refrigerant since last filter change. then you have to replace spin-on filter immediately! Over filter weight can cause the damage of compressor.
I wish this will help you to solve the the problem. if so, pls vote for it. Good luck!

My washing machine will not empty of water and this is preventing it from spinning.how do i empty the water via pump filter as i have no manual and it will not let me download one.please help!


This is could be caused from several issues. First I would try changing cycles on the timer to another spin cycle to see if that let the washer drain. Some times the timer malfunctions and doesn't allow the washer to spin. If this doesn't work and you can hear the motor running then you could have a broken belt or bad clutch or a wig wag (electric solenoids that operate the transmission.). The easiest way to empty the washer if it's located near a floor drain is to remove the drain hose from the drain and lay it on the floor near the drain. The water will run right out of the machine. If you not near a drain then you can use a Wet / Dry Shop Vac, remove the paper filter from inside the Shop Vac and then your ready to vacuum out the water. You will need to empty the vac several times.
Or you can use a garden hose and siphon the water out by place in one end in the washer and the other end outside or near a drain, You will need to **** on the end of the hose that's near the drain or outside. This will almost guarantee you a mouth full of laundry water so be careful if you try this.

GE Triton Dishwasher will not drain they water after it's cycle...thoughts?


Peace,
Cut off the power at the breaker for 5 minutes and then turn it on and see if the system resets!
The machine was in your home 3 years , and used for more than that by someone else! I can tell you by the model that its at least 10 years old!
appliances more than 9 years old cost you money to run and fix! Throw it out and do not put good money into bad!

The new ones no matter how inexpensive will wash better and cost you a hell of a lot less to operate. They are so much more energy efficient today that they pay for them selves in a couple of years! With a new machine watch your water and power bill go down!!!
Other wise you need hands on service!
if you got the money do it new!

Bless You!
