what could be wrong with a washer that allows drain water to return to the tub sometime after a complete cycle is over.it does not happen immediately but over a period of time. the wash water must be pumped up to a drain line as the washer is in the basement.
ANSWER Leea, Are you sure it's "dirty" drain water ? It could be a "seaping" fill valve 205613, allowing "clean" water to drip into, and fill the the wash tub in the OFF position. There is a "slight" possibility that the siphon break 206638 has failed and allows the water to syphon back in the tub, but that also indicates you need to have your drain pipes cleaned. Try shutting off the water faucets to the washer, when it's not in use (for a couple of days) If there's no water in the tub, you have a faulty fill valve, if there is water in the tub, you need a plumber to clean the drain pipes.
