@hf3 - I purchased my unit back in late 2019 and I've run into the exact same problem. Were you able to find out what was the cause of this or how to repair?Also, I've disassembled the motor — no signs of water damage or something like that. The unit's behavior is the same as inside the cleaner: impeller motor starts, then two cycles of the drive motor (forward and backward), then one more impeller motor run, and then nothing. The green diode on the PCB continues to blink uniformly.
Moved from here.
