HEAVY DUTY WASHER AND DRYERS
Their is usually no difference, and we can thank Westinghouse and Frigidaire for this nonsense as both of these companies started this in the early to mid 1960s. WH started calling their machines HD and Frigidaire called their 1963 line the Sturdy Washer. And the rest is history, even MT came out with little stickers in the mid 1970s that we applied to the machines on the sales floor because they were getting beating up buy the other makes that said HD. Some customers would tell us if these are so good and they are so expensive why aren't they HD like the less expensive WPs.
I even had one lady who was interested in the A207 but started it is just my husband and I that I wash for, I don't want a HD machine. I sold her the washer and promised that hers would be a regular model knowing that none of the MT washers in the warehouse actually had these stupid stickers on them. We also had a few complaints that when people did get their new machines that their machine did not say HD, so we had to tell them that MT forgot the sticker and send them a sticker.
Back to the original question, most manufacturers justify the Heavy Duty label buy telling you that the same machines are used commercially, which is largely true.
