Cal Coop 107 overheats after pump change

Postby JJFlash » Wed Oct 05, 2005 10:12 pm

California Cooperage model 107 - built 2001?
230v dedicated circuit
Balboa DU-107-DCA
electronic control
two AquaFlo XP2 - one 2 speed, one single speed
thermostat push topside
electric heat 2"

Main two speed pump suddenly stopped working - impellor was frozen solid and had obvious slow water leak as minerals caked-up on housing. Replaced motor with new AquaFlo XP2. High / low topside switch works normal for pump. Upon restart goes into filter cycle in high speed instead of low speed. Every filtration cycle now runs at high speed. Water overheats with "OH" on panel. Thermostat set on 80 degrees now; heats to 105 degrees. Local spa tech says bad circuit board. Board marked:
Balboa Inst. Inc.
S/N 51666***200006140054
Board 105 / 107 Coleman Dig Dup
Questions:
Does this sound like circuit board problem?
Should I replace only the circuit board?
Is #51666 the correct model number of this circuit board?
If so this board is apparently no longer made.
What is the replacement circuit board model number?
Thanks,
JJ

First get the speeds right, you should be able to switch the red and black wires to get filtering on "low".

A pump running on "high" speed could be giving you the extra heat.

Now there was some really bad advice.
Switched the red and black wires as recommended.
When I turned the spa back on it blew the main circuit breaker on the dedicated 230v panel.
Now I have no motors at all.
Topside panel comes on, but no motors.
Can hear the relay click when trying to activate motors from topside panel.
black - ground
red - hot
white - hot

Your black wire is ground on your motor?!?!?!?!?!?!?!?!?!? That is wrong, very wrong, very very wrong. your green should be the ground and the black and the red dictate low and high speed and the white is the common line. I can see why you blew the breaker and possibly the board, it's nothing to do with bad advice, it looks like someone simply wired your system way incorrectly and therefore when the proper advice is given the wrong wires were moved. I'm sorry to hear this but it should not have been wired that way to begin with.

Thanks TopTech, appreciate your reply. My sincere apology. As you pointed out was good advice but with unfortunately disastrous results for me. I was totally bummed when this happened as might be expected.

Now I am not sure on the wiring of the tub, whether it is done properly or not. Can you give me directions on proper testing of the incoming wires to verify is done correctly? Looks like this is the place to start.

Thank you,
JJ
