This is a list of things we recommend you do yourself or have done by a certified BIOROWER technician. If you do maintenance work yourself, and need help, we happily support you with growing list of videos and through video calls. The 5-year-service, however, definetely should be done by a certified BIOROWER tech. It helps to increase the usable lifespan of your BIOROWER and it also prolongs parts of your warranty for another five years.
The term “hours” refers to time in use, the additional mentioned time period of a week, month, a period of months or years is the latest recommend point of time to perform the specific maintenance.
