Teka ADW6-45FI (VROI)

Help please. Got a Teka slim b/in d/w. From left to right there are 5 functions: rinse only,glasses,eco,normal and intensive. Problem is no go with the glass and normal lights on but NOT flashing, the intensive light IS flashing.To be honest I got the machine to work in the end by lifting up the o/flow base float to get it to pump out-there was no water in base, bone dry. I tested the machine on glasses wash and it worked to the end fine- so in other words it fills ( to a normal d/w level) ,washes, soap disp opens, heats, pumps out, refills, ect….to end bleep bleep! Question is why did this go wrong in the first place? Presume lights on code = no pump out for some reason though what`s the reason? Anyone got an idea because I`m sure that it`ll go wrong again within weeks. I checked the wiring loom and it is ok, the disp solenoid works, but can`t see the suppressor- may be this jerking around-didn`t pull machine out though, heater works, thermistor works to correct temp-baffled???
