Wash Select II constant beeping

[Washbravo]

Hi all,

We are troubleshooting a Wash Select II that emits a constant "BEEEEEEEEP" type tone. It can be turned of for awhile by power cycling the unit, but returns within hours. My distributor that knows Unitech, and Washcard, are both stumped. We have isolated (we think) coin pulses from the washcard terminal controller by removing the "input/output" wires that go from the Washcard terminal controller to the Unitech board.

Any help would be appreciated. We also get intermittent card reads, but i think that might be a card reader that is wearing out.

Thanks.

Could a button be stuck on the keypad?
