Evaluation summary: operational tests were performed and the report of the device spontaneously turning on and off was observed.
During visual inspection, the keypad flex cable was found to be discolored.
The reported condition may be related to the issue of keypad flex cable degrading which causes an intermittent short circuit.
As a result, an unexpected power "on/off" cycling of the pump can occur without a key press.
The keypad will be replaced and tested prior to being returned to the customer.
