Quick follow up..

I'm scared its more an access 4 problem than the switches, just wanna have your thoughts..

Today its like nothing had happened the wave works perfectly its weird. If its the switches then code 253 would have appeared again? Since it seems like an intermittent problem then maybe more an access 4 problem?

Also, last night I worked very much with the wave and the code 253 was kicking in every time the wave was turned on. I could turn it off then when I turn it back on bam! Beep code 253. Then I had to drive forward at the max speed (but it was very slow like when you drive in mid air) and after maybe driving for 25-30 feet the wave started to get his speed back normally and the code disappeared and all was good. Turned it off, wait 1min then turn back on and instantly code 253 again.

And today NOTHING and its runing for 2-3 hours now non-stop

Could this be more an access 4 problem or more switches?
