Explanations of Error Codes
Display or Action
Explanation
E1
The door latch lock safety circuit is not responding properly. This error
indicates that three conditions exist simultaneously:
• The door is closed.
• The controller enabled the specific output which locks the door latch to
prevent opening the door.
• The controller sees the input which indicates that the door latch is
not
locked.
This error condition can occur any time the machine has power after the
power-up delay expires. The attendant must clear this error (see Section
4.1.1), then the formula is terminated.
Note 7:
The door latch lock is normally activated 60 seconds after the customer or
attendant starts a wash cycle. The timer resets to 60 seconds each time the door is
opened and subsequently closed. The door latch remains locked for 100 seconds
after the wash cycle terminates normally, to allow the basket to coast to a complete
stop.
E2
The coin switch is not responding properly. Specifically, the controller
expects the coin acceptor device to represent each coin with an input pulse of
a specific duration, and for each coin pulse to be separated from the previous
pulse by at least one half second. This error requires the attention of the
attendant.
