Tub was plugged in and a leak in a connection caused the water level to go down to a depth of about 5 inches. When we discovered this, the unit was still plugged in, the indicator-temperature light was on, but (of course), no action happening at the motor unit. As we are moving the tub, I have not refilled/reconnected. Now I'm scared that we've got a motor that is ruined Do you believe this damaged the motor on my newly purchased used Softub OR Is there any chance that the motor is ok?
