bottom Combi Oven giving problems, found water lines run from top to bottom oven going through side panel and side shield. Advised customer to move plumbing before I took pictures. 12-18-18 examined unit, Chris says gas reset button will consistently trip 3 to 4 times a week. checked error log only 1 in 5 years an e94 communication error removed and cleaned all connectors between boards, started and ran unit, no problems, ran steam and heat - called Rodger at Alto Shaam, confirmed gas pressures okay. Ignitor should be 9ma measured 5to7 sometimes lower, will order ignitor and gaskets. 1-16-19 removed and replaced ignitor unit, would not fire up (too short) cleaned carbon from old and reused, now getting 9 ma, turned unit on and tested, all okay.
