Pump failure after one year on Siemens SN65ZX07CE
A Czech user review on Alza.cz (rated 4.0/5 from 6 users) reports the pump died after one year. The reviewer notes that newer pumps from Siemens and Bosch are designed for low consumption and noise but are more sensitive and fail faster. This is a verified-purchase owner report of a major component failure.
What to check. The circulation pump is a critical, expensive part. If it fails after the warranty period, expect a significant repair bill. Consider extended warranty coverage for this model.
Siemens official: E31/E15/E3100 = water protection system activated
Siemens' own German support page states E31 (along with E15, F15, E3100) means the water protection system is activated. This corroborates the owner-reported E31 on the SN65ZX07CE and confirms it is a water-leak safety trigger, not a software glitch.
What to check. Treat E31 as a potential leak. Siemens explicitly advises against self-repair for health/safety reasons: close the water tap, switch the unit off, and book a service visit. Expect a technician diagnosis rather than a user fix.
Bearing failure causing noise on Siemens SN65ZX07CE
In a Swedish forum thread about a noise issue on a SN65ZX07CE, another member (sessions32) reports having the same problem and that it was a broken bearing that was repaired under warranty. This is an owner-reported mechanical failure requiring warranty repair.
What to check. If the unit makes unusual noises, a bearing may be failing. This was covered under warranty for the reporting owner; check your warranty status early.
Onliner.by's AI-generated summary of verified reviews for the exact SN65ZX07CE lists recurring minor complaints: the detergent dosing system sometimes leaves tablets undissolved, the touch control can respond with delay or error, the cutlery basket fixation is poorly designed, some programs run long, and plastic items stay wet even after intensive drying.
What to check. These are low-severity usability annoyances rather than failures. If tablets come out undissolved, check loading and the detergent dispenser flap; if the touch panel misbehaves, it may be a sensor sensitivity issue. None of these should stop a purchase, but they set expectations on drying of plastics and program length.
Onliner.by aggregates verified owner reviews and notes the detergent dispensing system sometimes leaves tablets undissolved. This is a recurring, user-visible quality issue.
What to check. If tablets are left undissolved, check the detergent dispenser flap and ensure the tablet is placed correctly; this may be a design limitation rather than a user error.
Water drops remain on plastic dishes even after intensive drying
Onliner.by reports water drops remain on plastic dishes even after intensive drying. This is a common limitation of dishwasher drying systems with plastic items.
What to check. Plastic items may come out wet despite the Zeolith drying technology; this is a known limitation, not a defect.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
