Miele 7278420 S7 / U1 Foot Switch Handle Release – Genuine Upright Lock Release Part
Genuine Miele S7 / U1 Foot Switch Handle Release – Part #7278420
This genuine Miele foot switch handle release is designed for select Miele S7 and U1 upright vacuum models. This part helps lock the vacuum into the upright position and releases the handle when the vacuum is reclined for vacuuming.
When the vacuum is moved into the vacuuming position, this handle release mechanism makes contact with the internal switch that allows the brush roller to operate. If the handle release becomes worn, it may not make consistent contact, which can cause the brush roller power to cut on and off while vacuuming.

Basic Troubleshooting Tip
One way to help identify this issue is to recline the vacuum into the vacuuming position and carefully move the handle release pedal up and down. If the brush roller power cuts in and out while moving the pedal, the handle release may be worn and not making proper contact with the internal switch.
Professional Installation Recommended
This is an involved repair that requires disassembly of the vacuum. Professional installation is recommended to make sure the handle release is installed correctly and that it properly contacts the internal switch when the vacuum is reclined.
