What changes a Junkers / Bosch repair bill
- Brand tier — Junkers - sold under the Bosch name for some years now - is fitted in a good many Belgian homes, often as an older instantaneous water heater or wall-hung boiler. An original control board for the Top 22-28 ZWB costs EUR 432.37 incl. VAT at a Belgian parts supplier, against EUR 396.76 for the Bulex reference board. A burner control unit for a Junkers instantaneous water heater costs EUR 465.00 there. Its spare parts therefore sit about a tenth above the reference. Board-derived: 432.37 / 396.76 = 1.090, rounded to 1.10. One observed like-for-like main board (BOSCH PRINTPLAAT VOOR TOP 22-28 ZWB-TOP 42 ZWB 87483005630), price incl btw as published by VEPA Sanitair. Corroboration only: besturingsautomaat WT10/11 EUR 465.00, drukverschilschakelaar EUR 269.20, binnenwerk driewegventiel EUR 89.08, automatische ontluchter EUR 36.22. The drukverschilschakelaar figure is the standing comparator used for Itho Daalderop's druksensor.
- Parts vs labour — the brand and tier shift the parts price; labour tracks your area's wage index, not the brand.
- The specific fault — a sensor, seal, or valve is far cheaper than a compressor, motor, or control board.
- DIY vs professional — Some Junkers / Bosch faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
