Whirlpool water softener repair question?

my whirlpool water softener model WHS30 stop working with a water overflowing since the drain pipe was not installed properly. The plastic pipe that goes over the softener to the drain was too narrow and cracked and the connection. water was spraying to the control panel and short it out. it is very easy to replace the panel and it cost $136.00 non refundable. the pipe is also easy to replace. My question is, can water spraying cause other equipment to fail like the the motor etc. in that case it is probably not worth fixing it. if you don't know much about watersoftner please don't reply.
