Sewer gas smell every time the tub is emptyed

Confirm that the sewer trap is working. The sewer trap for a washer is the pipe connection where the washer drain hose connects.

It would not be likely that the trap is a problem. Sewer gas and mold can smell similar. Smell around the hose connection. Some older homes just simply had a drain to the outside
Next this machine is a top loader and if it is being used several times a week the problem is likely around the tub on top. Mold will form in the tub under the basket if it is not run weekly. Normal wash cycle in a top loader should keep under the basket clear. If a week or so occurs between use then the problem can be under the basket at the bottom of the tub. Use bleach, vinegar, or baking soda in moderation to clear.

It is more likely that the problem is around the top of the top. this requires opening the top and swinging it back to get access. Make sure power is removed before attempting.

Cleaning a little bleach, soap and water.


this helps?

If the house has been sitting for a long time, the traps may have dried out and are not stopping the sewer gasses from being trapped back, flush all toilets and run some water in all the sinks and tubs, to refill the p-traps, also don't forget to pour some water down the washer drain pipe. HOPE THIS HELPS...

Freon is odorless. A sewer odor could be caused by an unused sink, tub, or floor drain trap where the water has evaporated. A gas odor is a very serious issue that should be checked immediately by the gas company or the fire department. Gas can seep in from a leak outside the house or accumulate in a wall if a fitting fails.

The smell is sewer gas coming back in the house from the sewer or septic tank ether from a dried out water trap in a floor or fixture drain, or from the roof vent, or a hole or separation in pipe or fitting. Like wax ring under toilet. First pore water down every drain to fill any trap that might have gone dry, then flush toilet or run washer or drain bath tub.This will displace gas in pipe and will cause the smell to increases if there is no smell then the problem is fixed if not check roof vent it may need a charcoal filter on top, There is no water trap on air vent on roof and is an open hole to the sewer or septic, The heating system in the winter or AC in summer will draw the gas inside from the vent.If it is the vent you should be able to smell it from outside. If all tests fails You will need to have a smoke test done. A smoker is set up outside and the line is filled with smoke and will show where gas is coming from. Also it might be a good ideal to check all gas fittings in case it is a gas leak.

The tub is probably pretty dirty. Try cleaning the washer with CLR.

the switch is a service or emergency switch if the condensation hose / line is not a sealed connection and the trap is empty the sewer smell will be constant either make it a sealed connection or close off the trap and reroute the condensation line --during heat season not condensation so heat will cause water in to evaporate

Sounds like you have an intermittently blocked vent pipe (the one that goes out through your roof). If there is gas pressure in the downstream sewer line and it can't get up through the vent, it could bubble up through your toilet or sinks. I would get up on the roof with a few jugs of powerful drain cleaner and dump them into your vents. You might also run a few dozen gallons of water down those vents after the drain cleaner has had time to work.
Good luck!

hiya:) all tubs,sinks,etc are plumbed w/a P-trap which holds water and prevents sewer gasses from venting into your home. if the unit has not been used in a while the water may have evaporated, allowing the sewer gas to pass freely into your home. this is not only unpleasant it is potentially dangerous and/or unhealthy. IF the unit has not been in use for some time then just run the water for a min and the smell should go away. If this is not the problem just text me back and we'll go from there:)

I hope you put trap back on,or you need to fill trap with water--that is the water seal for sewer gas

Something was flushed that should not have been flushed
You will have to have your drain snaked out.
