Water drains out of washer on fill cycle. Noticed that water was trickling through drain hose a few weeks ago then it stopped. Put clothes in washer last night before bed and this morning washer was still trying to fill but all the water was running right out the drain at the same time. Easy fix? Thanks… TCH
Easy fix! Yes!
Somehow you have created a siphon either because the hose is too low in the drain pipe, or you have sealed off the drain pipe so no air can get into it.
That should do it.
That was it… my drain is set up to a hose in the yard and it was slightly "up hill" not letting it vent. Thank you very much!
