Hi guys, came home from a weekend away to find out our house had been hit by lightening. We have no hot water/heating from our eco tec plus 637. The wired thermostat showed 'com err' (communications error). The boiler itself seems ok but is displaying errors S.0 (no request for hot water) and S.7 (pump over run). The control box green light is flashing slowly (ebus issues). We have replaced the thermostat and control box but the fault continues. My engineer is stumped. Would really appreciate any advice, thanks.
