Digitech Digidelay Repeat problem?

[Kimon]

Hello everyone.

I am experiencing a strange issue with Digitech Digidelay and would like to be able to confirm it is indeed a fault:

When the "repeat" knob is at "10" (full on) https://speedtest.vet/ https://vidmate.bid/ there seems to be no repeats at all - only dry signal.
Backing it to about 8-8.5 brings on the delay\repeats as they should.

I cleaned the potentiometer (even though is is a sealed type square pcb mounted type) to no avail.

Is my copy defective? Have any other members experienced the same behavior?

Thank you in advance.

Don't have one, but that sure sounds like something is wrong with the pot.  Cleaning can't fix everything.  How old is it?
