Estoy seguro de que sigo intentando saber más sobre ellos antes de tomar una decisión.

Tenemos este ascensor Diethelm en nuestro nuevo edificio de apartamentos desde finales de 2024 y, francamente, es una vergüenza. En casi un año de funcionamiento, el ascensor ha tenido problemas en repetidas ocasiones, a veces durante períodos prolongados. Aunque las averías son menos frecuentes ahora, la situación dista mucho de ser satisfactoria. Lo que sigue siendo completamente desconcertante es la velocidad. Este ascensor es, con diferencia, el más lento que he utilizado. Para ser un edificio nuevo, parece completamente anticuado. Cada viaje parece una eternidad, aunque sea por unos pocos pisos. Es extremadamente inconveniente para el uso diario y no parece ni moderno ni contemporáneo.

An outrageous company that left me stuck in the elevator for an hour after I called for help. This is a long-standing problem where the elevator sinks down and doesn't reach the correct position, and it's been going on for two years. Unfortunately, this company is characterized by incompetence, unreliability, and poor quality, and they seem unwilling to take the issue seriously and unable to find a proper solution. There are children and babies in the building! How negligent can you be when it comes to maintaining an elevator like this? Absolutely pathetic!

I live in a seven-unit building with a Diethelm elevator (for about 16 years). The elevator breaks down regularly. Although service work is billed, this leaves much to be desired, as necessary cleaning of sensors, etc., is not carried out. Our apartment building incurs high elevator costs, and we are very dissatisfied. Three weeks after the service, the elevator is not working again, and error messages are not being followed up. A second company we called in investigated the problem, but no cleaning work was carried out. I cannot recommend this elevator company to anyone.

Such a message (see image) can remain displayed for several weeks on a Diethelm elevator! And this in a relatively new, wheelchair-accessible building. Regular maintenance by the same company has failed to either fix or detect the problems (which have clearly existed since the elevator was installed). I am very disappointed. Based on the company's responses to previous comments, I would like to clarify that this concerns the elevator at Theaterstrasse 27c in Winterthur. They do not appear to feel even the slightest responsibility for the resulting extended outage. Update: August 26, 2025: Thank you to Diethelm Elevators AG for following up and taking the matter seriously. According to feedback from tenants, there have indeed been no further incidents in recent months, and the elevator has been operating without problems. Hopefully, problems will be identified early in the future, normal wear parts will be proactively replaced, and functionality will be ensured through regular maintenance. I would be very pleased if Diethelm Aufzüge AG felt responsible again for the functioning of its products.
