What changes an Ariston repair bill
- Brand tier — Ariston is an Italian entry-level brand that in Belgium turns up mainly in apartments and in renovations. At a Belgian parts supplier its common parts sit clearly below the reference level: an automatic air vent costs EUR 22.83 against EUR 57.91 to EUR 92.72 for the same part from Bulex, a built-in expansion vessel EUR 102.25 and a Microalfa expansion vessel EUR 146.53 against EUR 250.60, an ignition electrode EUR 24.14 and a 3-bar safety valve EUR 24.42 against EUR 27.71. All incl. VAT. Basket-derived and floor-clamped. No Ariston control board observed, so the factor rests on wear and hydraulic items compared like-for-like at Belgian shops: automatische ontluchter 22.83 / Bulex automatische ontluchter median 75.32 = 0.303; inbouwexpansievat 102.25 / Bulex expansievat 250.60 = 0.408; expansievat Microalfa 146.53 / 250.60 = 0.585; veiligheidsklep 3 bar 24.42 / Bulex veiligheidsventiel 3 bar 27.71 = 0.881; elektrode ontsteking 24.14 / ACV BLOCGAZ ontstekingselektrode 58.08 = 0.416. Median of the five = 0.416, well below the 0.85 floor, so clamped up to 0.85 with the raw reading printed. The Bulex safety-valve comparator is BekaTech's veiligheidsventiel 3 bar 0020275016 at EUR 22.90 excl btw = EUR 27.71 incl btw, and it is cited in the sources below.
- 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 Ariston faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
