Too much foam in a Speed Queen TR7 is nearly always too much detergent or the wrong detergent. Speed Queen's guide calls for low-sudsing high-efficiency (HE) detergent, says to use only half of the label amount if you use a non-HE product, and describes an oversudsing condition that shows as the Wash and Rinse lights flashing three times after the cycle until you open the lid or press Start/Pause. An overloaded tub adds to it, because clothes that cannot circulate hold soap in the load.
Differential
Likely causes of “Speed Queen TR7 top-load washer shows excessive suds, SUD or Sd behavior”, and how to tell them apart
- 1
Too much detergent for the load
What separates it Foam at the lid, and the Wash and Rinse lights flashing three times at the end
How to confirm Check the label dose for a top-load HE washer and cut the amount by a third on the next load
- 2
A non-HE detergent in an HE washer
What separates it Heavy suds from the very first fill, worse in soft water
How to confirm The guide says to use only half of the manufacturer's recommended amount of non-HE detergent, or switch to an HE product
- 3
An overloaded tub
What separates it Suds plus wet, tangled clothes at the end of the cycle
How to confirm Keep dry loads under the guide's 16 lb limit so items move freely through the water
- 4
Detergent left in a load or in the tub from earlier washes
What separates it Suds keep appearing in the rinse even with a normal dose
How to confirm Run an empty warm cycle with the right amount of HE detergent, then a Spin Only cycle
Before you touch a setting
Record this first — changing settings destroys the evidence
- The detergent brand, whether it is HE, and how much went in
- Whether the Wash and Rinse lights flashed three times and when
- How big the load was and which cycle and temperature were used
Try in this order
0 of 5 completedClear the suds-lock code
ReversibleOpen the lid or press Start/Pause. The guide says the three-flash pattern stays on after the cycle until one of those happens.
Rinse the suds out
ReversibleAdd Extra Rinse and run the load again, or run Spin Only once the suds have collapsed. Cold rinse water is normal on the TR7, including with optional rinses.
Reduce the detergent
ReversibleUse the HE amount on the package for a top-load washer. If the only detergent to hand is not HE, use half of what its label recommends.
Reduce the load
ReversibleLoad loosely under 16 lb, and wash heavily soiled or very absorbent items in a smaller load so the water can circulate.
Test with a small load
ReversibleRun a small load with measured HE detergent and watch the first minutes of agitation for foam at the lid.
Model-specific
What is true of this model and not of its siblings
- Suds and the final spin

Exact questions
Common questions
What do the Wash and Rinse lights flashing three times mean on a Speed Queen TR7?+
Speed Queen's guide calls it an oversudsing condition. The pattern shows after a cycle until the lid is opened or Start/Pause is pressed.
How do I clear the suds code?+
Open the lid or press Start/Pause. If lights keep flashing after that, unplug the washer for 15 seconds.
How much detergent should a TR7 use?+
Follow the label for a high-efficiency top-load washer, and use only half of the label amount if the product is not HE.
Why does the TR7 need low-sudsing detergent?+
The washer fills only to the level the load needs, so suds that would drain away in a deep-fill washer stay in the tub.
Can too much suds stop the spin?+
Yes. Excess suds are one of the guide's three causes for the washer not reaching its maximum speed in the final spin.
Does an overloaded tub make more suds?+
Overloading is listed with detergent as a cause of oversudsing, so use proper load sizes.
