What changes a De Dietrich repair bill
- Brand tier — Four class-confirmed product pages, all De Dietrich gas-boiler control electronics, all priced: carte électronique 7693835 at 188,40 EUR TTC (0.47x, more than 5 in stock, listed for chaudière MSN 24 MI CF), platine PCU-03 + SU 7649094 at 524,40 (1.31x, more than 10 in stock), platine SCU 04 7601096 at 535,20 (1.34x, more than 5 in stock), carte électronique 97904505 at 1 075,20 (2.69x, listed for chaudière DIETRISTAR DD1.24 / 2.24). The two platines carry no appliance list on their own product pages; their class is established by the retailer's MCA 25-28 BIC parts list, which is cited as a fifth source and shows both parts at exactly these prices in a De Dietrich condensing gas boiler. Median ratio 1.3243, rounded to 1.30 -- the median rather than the mean specifically so the legacy Dietristar board at 2.69x does not dominate. Excluded: carte principale 35 (7693654) at 333,60 EUR TTC, which is listed for the De Dietrich MOSE outdoor module and the Oertli OE Clim MONOSPLIT MXN -- air-conditioning hardware, not a boiler. Also excluded: 7719088 (304,80, listed for CESL chauffe-eau), 300019916 (63,80 EUR HT open-therm interface, auxiliary), 7672771 and JJD710688600 (obsolete, unpriced), platine display iSystem S101249 (a display), and the PSU parameter cards at 51,60-56,40 EUR TTC (not control boards). The retailer's search index still shows 97904505 at 816,00 EUR HT; its product page reads 896,00 EUR HT / 1 075,20 EUR TTC, and the page figure is the one used.
- 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 De Dietrich faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
