Bosch SGS45A02GB/36 DISHWASHER Not cleaning correctly

Didn't look like it had cleaned at all, even the pots that had been rinsed looked like they had scum over them. Cleaned filters and both spray arms. Added a gallon of water to bottom of tray but was close to lip anyway.When I opened door 5 mins into auto cycle notice there was no heat, top spray had a lot of water coming out but didn't appear to be spinning. bottom arm had nothing coming out. Couldn't find detail in guides ( but these are the best on net I have seen so great job ) Any pointers would be most appreciated. Its an old m/c but cant afford a new one under current financial climate.Kind Regards

I will try and help with this problem Bosch SGS45A02GB/36 DISHWASHER

if you have water coming out of the top spray arm then this means that the motor is running correctly, you need to check the bottom spray arm,  also take the spray out and see if there is water is coming out at pressure, you will need to use a Multimeter on the heating system to check if the heating element is good. but i have sent my contact details to call if you get stuck
