No, I'm not using too much soap. I put in very little and still have a problem. And it's not the type of soap either, as I've used all kinds, both HE and non-HE. Thanks for the reply, but it's not about the soap. It is a new washer and this didn't happen with the previous machine. But the appliance repair man says that it can't be the washer. It is a commercial washer with a center agitator. Perhaps it's just whipping up too many suds? But if so,then the pipes should be able to handle it, right?

It can be excessive soap for your water chemistry. If you have a water softener it could also explain it. It is possible that the washer standpipe is causing it, perhaps the water is coming out so violently that it is sudsing up and a 2" drain would have had the room to accommodate the suds and the 1.5" doesn't. I have seen suds push out of a floor drain, but never a washer standpipe… unless your washer isn't connected to an actual standpipe.

then have a good cry as the newer machines have a higher rate of discgarge

A "Commercial Washer" with an 1-1/2 discharge pipe? Me thinks you need a much larger standpipe for your Commercial Application. Most commercial washing machines use open trenches for discharge.

Hi Everyone,

Thank you for your responses. So here's the update. I had my plumber replace the drain behind the wall. He put in 2" pipes. We thought that would do it. We ran a load, and sure enough in the last 2 minutes of the cycle, suds started popping out of the standpipe. So, i'm just looking for someone to agree with me that this is a washer problem. It's not that my machine is defective, it's that it's too powerful a machine for a home. It is a Speed Queen washing machine. And those are probably best used in laundromats or apartment complexes because of their speed. The water discharges so forcefully out of the drain hose, it's almost scary.

I went back to the appliance store today and asked them to exchange the machine, saying I need a less powerful machine (I had a energy efficient Maytag before and had no issues). They were quite rude, saying I'm using too much soap. That's not true -I've been doing laundry for 30 years and know how much soap to use. They are insisting on having a repair man out to the house. Ugh! I've been dealing with this for a month and just want a normal household machine! Any advice is greatly appreciated.

I thought you wanted a answer and a solution to the problem. My bad.

you may have a partial stoppage, if not:

you may be discharging the speed queen into a suds pressure zone

the previous machine(s) may have been such junk that it made no difference

I have a 2014 top loading speed queen myself, but, it does NOT discharge into a suds pressure zone

It's your soap! I bought a new Speed Queen T5 Top Load, Non-HE Washer and matching dryer. I experienced the same issue. At first, I thought the washer wash leaking. This went on for months, and I had the service guy out several times. Long story short, it turned out to be the laundry detergent. No matter how little soap I used, during the final spin, I would have soap suds coming out of the top of my drain pipe. The water that I thought to be coming from a suspected leak turned out to be the soap suds liquifying upon contact with the floor. They would ooze out the drain pipe opening, run down the wall and liquify upon hitting the floor.

After talking with several people, including a sales person at the appliance store from where I purchased the pair being the last, it was determined to be the brand of soap. I was using the Seventh Generation Fragrance/Dye free Laundry Detergent. Apparently, this soap has a tendency to create a very large amount of suds regardless of the amount of soap used.. Obviously, more soap equals more suds. The sales guys experienced the same issue with his front loader.

The solution is to run washer through a full wash/rinse cycle with an extra rinse using only plain, hot water to rinse away any residual soap residue. The second step is to switch detergents. The recommended detergent is the Persil BLUE liquid. For the Speed Queen, the recommended amount of soap is just 1-2 tablespoons! DO NOT USE PODS!! If you have a water treatment system, such as water softener or an water ionizer, cut the amount of soap by 2/3!

Another solutions is to cut a sponge just slightly larger than the pipe opening. This will fill in the gaps and block the suds. I just cut an "+" in the center of the sponge to insert the drain line coming from the washer. Being a sponge is porous, it allows for the passage of air during the drain cycle but does not allow for the passage of suds during final spin. Yet, the only fear I have is for the sponge to fall inside the pipe creating a clog should have to remove the drain line from the pipe. Yet, I guess one could tie a string around the sponge to allow retrieval should this happen. Just make sure the string is long enough to dangle on the outside of the pipe. I would say twice the length of the pipe between the pee-trap and drain opening, like 4 feet or so. However, I am going to just switch detergent and call it good!
