Dishwasher repair statistics
The dishwasher is the second most repaired appliance: 224,554 interventions recorded in the Archimede management system from July 2019 to March 2026, accounting for 24.8% of all interventions (906,994 total). Nearly one in four.
Compared with the washing machine, the dishwasher has a markedly different profile: one dominant brand (Bosch at 16.1%), error codes as the primary reason for contact, and a single code — E15 Bosch — that alone generates more reports than any other fault in the entire Archimede database.

Most common faults
"Won't start" is the most reported fault, followed closely by "error code" at 14.3%. Together, these two reasons account for nearly a third of all requests. The picture is more concentrated than for the washing machine, where the top four faults were almost level.

Most repaired brands
Bosch is the most repaired brand by a significant margin — nearly double the second-placed Electrolux at 10.6%. For washing machines, no single brand exceeded 10%. Bosch also has the largest installed base of dishwashers, which explains the dominance. Brand distribution reflects market share, not reliability.

| Brand | Interventions | % |
|---|---|---|
| Bosch | 36,137 | 16.1% |
| Electrolux | 23,869 | 10.6% |
| Whirlpool | 20,108 | 9.0% |
| Ariston | 19,882 | 8.9% |
| Miele | 16,802 | 7.5% |
| Candy | 13,891 | 6.2% |
| Rex | 13,576 | 6.0% |
| Smeg | 12,188 | 5.4% |
| Siemens | 11,047 | 4.9% |
| Indesit | 8,016 | 3.6% |
| Beko | 6,984 | 3.1% |
| AEG | 5,215 | 2.3% |
| Franke | 4,627 | 2.1% |
| Ikea | 3,812 | 1.7% |
| Samsung | 3,562 | 1.6% |
| Hotpoint | 3,172 | 1.4% |
| Neff | 2,676 | 1.2% |
| Others | 18,990 | 8.5% |
Worth noting: Bosch and Siemens together (same BSH Hausgeraete group) account for 21% of interventions. Adding Neff (also BSH) brings the total to 22.2% — more than one in five. Rex, Electrolux, AEG and Zanussi (Electrolux group) together reach 20.9%.
Most frequent error codes
The dishwasher is the appliance where error codes are most prevalent: it occupies 7 of the top 10 positions in the overall ranking. E15 Bosch is the single most reported error code in the entire Archimede database, with 4,429 occurrences — nearly four times the second-placed code.
| Code | Brand | Fault | Occurrences |
|---|---|---|---|
| E15 | Bosch | Alarm | 4,429 |
| E15 | Siemens | Alarm | 1,275 |
| I30 | Electrolux | Won't drain | 1,126 |
| F70 | Miele | Water leak | 1,099 |
| E19 | Bosch | Won't start | 1,052 |
| F11 | Miele | Won't drain | 1,037 |
| E09 | Bosch | Won't heat | 1,029 |
| E24 | Bosch | Won't drain | 710 |
| F24 | Miele | Locks up | 634 |
| E25 | Bosch | Won't drain | 539 |
| F06 | Whirlpool | Won't fill | 515 |
| F14 | Miele | Locks up | 472 |
The ranking is dominated by two brands: Bosch (5 codes out of 12) and Miele (4 out of 12). E15 is shared between Bosch and Siemens (same group) and indicates a water alarm in the base — typically linked to the anti-flood sensor. I30 on Electrolux has the same meaning. Miele appears with four different codes (F70, F11, F24, F14), a sign of its more granular on-board diagnostics.
Fault profiles by brand
Each brand has a distinct fault profile. The most striking finding: on Bosch and Miele, the leading fault is "error code" — the customer calls because the display shows a code, not because of an obvious functional problem. On Ariston, the top fault is "won't start" at 20.4%, the highest concentration among all brands analysed.
Bosch — 36,137 interventions
| Fault | Occurrences | % |
|---|---|---|
| Error code | 7,800 | 27.8% |

| Won't drain | 1,565 | 11.0% |
| Won't fill | 1,516 | 10.6% |
| Locks up | 1,256 | 8.8% |
| Electrical problem | 1,035 | 7.3% |
Miele — 16,802 interventions
| Fault | Occurrences | % |
|---|---|---|
| Error code | 3,703 | 30.0% |
| Won't drain | 2,018 | 16.3% |
| Won't start | 989 | 8.0% |
| Water leak | 859 | 6.9% |
| Won't fill | 812 | 6.6% |
Worth noting: on Bosch, nearly one in three calls (27.8%) stems from an error code on the display. On Miele, the figure rises to 30%. Both brands have more sophisticated on-board diagnostics, which leads customers to call quoting the code rather than describing the symptom. Electrolux has the most balanced profile: the top three faults all sit around 13%. Ariston has the highest concentration on a single fault ("won't start" at 20.4%), suggesting a particular vulnerability around start-up reliability.

Source and methodology
The data covers dishwasher interventions recorded in the proprietary Archimede management system from July 2019 to March 2026 (224,554 interventions out of 906,994 total). These figures do not represent the appliance repair market as a whole, but the activity of service centres that use the software.
Brand distribution reflects commercial market share. A brand with a high number of interventions is a widely sold brand — not necessarily a less reliable one. Fault classification is based on what the engineer records at the time of the intervention.
