Blackcab, I'd have them look at the low level sensor first.From what I see is you will not be able to run in manual if you have low level/pressure upstream of your pumps. They've bypassed it to run the pumps in manual. I engineered in a laundry yrs ago and had booster pumps that required upstream pressure to run either in auto or manual to prevent pump damage. Your panel reminds me of the ones we had which were built by TRW, here is the US. Hope this helps.
