Zanusasi FJ1254W Reading the fault code

Hi Guys was at a Zanussi FJ1254W 914512815/00 washing machine for a letting agent, tenant is indian so couldnt explain in great detail what was wrong they have had the drain fixed for a blockage but the washing machine is faulty doing silly things, i put machine through diagnostics test it fills okay but when it heats with recirculation pump running after about 5 mins the 2nd and 3rd progress light flashes with last one also flashing is this an error code i think it might be 61 i’ve checked the ntc and wiring so i think it might be module JJ.
