This isn't the exact model, but I couldn't find mine. Machine was new in 2003 and about 2 weeks ago the drain pipe started overflowing during the rinse cycles. I've put Drano, Liquid Plum'r and even bought a snake with no success so I'm sure there isn't a clog in the pipe. If I pinch down on the drain hose the water won't overflow. It seems that the pump is putting out more water than the pipe can handle, but not sure how that could happen all of a sudden or how to fix it. Any suggestions or tips would be appreciated.

Re: Water Backs Up in Drain Pipe and Overflows
The pump will pump out at a continuos rate that wont change, the problem will be with the standpipe. You dont have to have a total blockage in the pipe, sometimes the diameter of the standpipe reduces due to scale build up and it just cant cope with the rate of flow.There will be a restriction somewhere.

The wall box outlet probably is about 1-1/2 in. in diameter. If it was snaked clear then there may be blockage in the main sewer line. In my case, there is a 90 degree bend that gets blocked periodically and causes the washing machine discharge to back up
Fyi. All new washing maching already tested on their functionality and features but not test run with water intake and drain function. I would like to share My experience last time with this model. The water outlet valve will release by motor when you set to drain mode.it suppose manage to retract back by spring when drain process finish or afte small you change to wash mode. Take a look on the spring movement.normally it not properly hold valve switch hence the retracted spring not block the valve to stop water drain. Just rectify the alignment of the valve swich which directly connected to the retractable spring.
Usually there is a clog or restriction in the stand pipe(drain pipe) causing water to not drain away.....Suggest drain-O products. If you have a very long drain or the stand pipe is not above the water level in the tub you will want some type of air gap to prevent siphoning.(siphon break kit)
Difficult if not seen. Most common water on the floor senario is a drain pump leaking:or a perrished pipe from friction.or sometimes, water backs up from the house drainage system due to a restriction.
2 ins is rather small and there may also be a partial blockage somewhere in the system you are not aware off.
a naughty cure is to restrict the drain hose of the machine so water comes out a bit slower
you don't you get a different plumber may only be a partial restriction in drain line and could be any where down the line water is pump out on some washer faster than a restricted drain can handle it and no there is no way to reduce rate water is being pump out..been there have the t-shirt
The problem with the new washing machines, is that they dump 20-22 gallons of water in 4-5 seconds. This amount is far more than the garden hose test will submit the drain to. Here are a number of solutions, I hope that one of these will help you.
#1 As mentioned above, you can restrict the flow of the drain pipe. I recommend a 3/4" x 6" brass nipple, or a 1/2" x 6" brass nipple, depending on your specific situation. The brass nipple will not corrode like a galvanized nipple.
#2 There is also a rubber cap that you attach to the drain pipe that fits around the drain hose tightly.
#3 Some situations might require that you have to raise your drain pipe. It is recommended that it be at least 36". This allows for gravity to assist the drain.
#4 Some situations will require that the drain pipe be increase in diameter. Older plumbing applications were installed using 1 1/2" piping. With the newer washing machine discharge volume, the 1 1/2" pipes will not support the discharge. Your drain line will need to be changed to 2". This option will be one of the more costly fixes, depending on the amount of line that needs to be changed.
#5 Some plumbing installations installed without a p-trap will need to be changed. The p-trap keeps sewer gas from coming back into the house. It also allows for a smooth transition into the drain line. Any restrictions in the drain line (i.e. ells, tees,) will cause the soap in the gray water to foam up which will cause the drain line to slowly back up.
