I haven’t seen the machine yet so only going off what the customers (who are also friends) are telling me.
Going back through the messages, they seem to mention afterwards it’s the 30@30 programme, not the wool programme.
They say that a higher spin speed works, but not the 800rpm, which sounds very bizarre to me. Presumably if any of the stuff you mentioned applied, it wouldn’t do the spin at 1200 or 1400rpm either.
I’m waiting to hear back from them if another programme that uses 800rpm works.
