How the calculation works
V17 calculation: maxWidth=openingWidth; maxHeight=openingHeight; maxBodyDepth=max(0,openingDepth-serviceRear); doorFits=doorOpenDepth≤aisleDepth; overallPass=maxWidth>0 AND maxHeight>0 AND maxBodyDepth>0 AND doorFits. The result is reported as Dishwasher fit.
Worked example
Example: Dishwasher opening width = 90 cm; Opening height = 87 cm; Opening depth = 60 cm; Rear service allowance = 30 cm; Door open projection = 60 cm; Available aisle depth = 60 cm. Result: Fits; Max Width = 90 cm; Max Height = 87 cm; Max Body Depth = 30 cm.
