Combi oven with no display

Alto Shaam.CTP7-20E 480VAC will not power on. Unit had a hose barb break on detergent pump, and it is never a good thing. In-house maintenance replaced the barbs and itbran for a while before having a blank screen. Went through the unit, and it's back in business.

Hi boss i have alto shaam combi oven. Ctp20-20e. The problem is no display light. What could be the problem?

[@commercial_service]

That damn fuse for the display. Why won’t they sell just 1. Why make you buy so many? The drain valve and that “y” care valve. 😤

[@CommercialKitchenChronicles]

Fuse was bad from the lower humidity valve being soaked in chemical. Those 2 15 amp fuses are all control side stuff

Hi boss, I have the same problem but I get error code E5? What's the problem?

[@CommercialKitchenChronicles]

E5 is generally a motor not spinning or vfd not sensing it spinning
