The gurgling sound when the washing machine drains is normal as long as there is no underlying cause.
A Gurgling sound is generally heard when the air in the P-trap is displaced by the incoming water. Additionally, if there is a blockage in the drain line between the washer and the sink, this can also cause a gurgling sound as the water tries to flow through the blockage.
Why do you hear the gurgling sound when the washer drains?
This is quite familiar to a kitchen sink that gurgles due to clogging or heavy stuff being drained along with the waste.
When your washer drains out the wastewater, it drains out the mixture of detergents residue along with dirt and untrapped lint i.e. the tiny fibers from the clothes.
The pressure from the drain pump lets the flow move through the narrow drainpipe usually creating a gurgling sound while reaching the sink.
It may also occur due to air blocks in the vent areas of the sink.
If the gurgle is unusual, then it is the right time to have a look at the sewage area of the sink for any blockages. The sink and the sewage area inspection is preferred by an expert or the plumber, as it may require sewage drilling equipment.
Most of you may have the washer’s drain connected to your kitchen sink which is quite common, here it becomes difficult to identify the cause of blockage caused, either by the washer or the kitchen waste.
If possible, it is always a good idea to separate the drain connection of the washer from other sinks.
