The model of this diode is SR2100, which is a Schottky diode compatible with BEKO Wash/Drier and replaces D7 in washing and drying machines. The original diodes were SR110 1 ampere diodes, which often experienced short circuit faults, leading to power outage symptoms. These diodes are SR2100, an upgrade of the original diodes, and SR2100 is a 100v 2Amp Schottky diode, which can handle twice the current of the original SR110 diodes that are prone to faults in these machines, greatly reducing the occurrence of faults. With the power turned off, simply remove the rear panel and access the main control board installed in the black plastic casing. Remove the original D7 diode and replace it with the SR2100 diode. Use a multimeter (if available) to check for a short circuit, then solder a new replacement diode (the gray band on the diode is on the same end as the original diode), and reassemble. This process requires professional circuit skills. If you do not have them, you need to seek professional assistance., Manufacturer: OTOTEC
