Page 21: Fill System
DIVA Service Manual - EDW 1503 4.3.2 Fill system The water fill solenoid valve is powered by triac TY2 on the electronic board (connector C7), by the door switch (IP) and by the anti-flooding microswitch (DA). The level of water in the sump is monitored by the pressure switch (RL). -
Page 22: Control Of Water Fill Phase
DIVA Service Manual - EDW 1503 Control of water fill phase The quantity of water required to perform the washing cycle is determined exclusively by the closure of the electrical contact of the pressure switch, which switches from EMPTY to FULL. -
Page 23: Dynamic Fill Time
DIVA Service Manual - EDW 1503 4.5.2 Dynamic fill time T.D. = T.S. x 3: This is the maximum time allowed for the entire fill phase within which the pressure switch signal must stabilize on FULL. If the pressure switch signal does not stabilize on FULL within this period (T.S. x 3), the electronic control system switches off the fill solenoid (and the heating element, if switched on), and then allows the washing cycle to proceed until it is completed. -
Page 24: Washing System
DIVA Service Manual - EDW 1503 Washing system The washing system is of the traditional type in which the mechanical washing action is provided by the rotation of the washing pump. The pump ducts the water into the hydraulic circuit, thus actioning both spray arms simultaneously. -
