Product details
Light gray to match the rest of the 370 Comfort's trim, part 20128ER is the pile adjustment knob — the piece you actually take hold of when the flooring changes underfoot. It is the visible end of the height adjustment train, sitting outboard of the lever and the axle that do the work inside the head.
Knobs get gripped hard and knocked against furniture legs, and the failure is cosmetic before it becomes functional: a chip, then a crack, then a knob that turns loose on its stem. From that point the height is being guessed at rather than selected, and a setting that once sat in a definite position becomes a vague place somewhere in the travel. A fresh knob restores a firm grip and a clean, repeatable position.
Colour is worth stating plainly, because on a part like this the finish is what separates one number from another. 20128ER is supplied in light gray, the shade SEBO used on the 370 COMFORT. Fitting it is a hand job rather than a bench job, and it is sensible to renew the knob at the same time as the lever or the axle when the whole adjustment mechanism is being gone through, since a tired knob on a new lever will feel no better than it did before.
The adjustment on this machine is manual, so the knob is not a decorative cap over a hidden mechanism — it is the handle that transmits your input into the head. That is why a knob spinning loose on its stem produces exactly the same complaint as a broken lever: the control moves and nothing else does. Checking which of the two has failed before ordering saves fitting the wrong part. If the knob turns and you can see the lever inside moving with it, the fault is further in; if the knob spins while the lever sits still, this is the part to order.
