Maytronics power supply 9995670-AU Repair

by Ron

Hi,
My Dolphin M400 Robot power supply 9995760-AU has died and I am trying to repair it, I have found a moisture short on the board and confirmed Q2 12N50NZ Mosfet has blown and also R16 on the back of the board. My problem is I can't read the resistor value for R16, does any body know the resistor value or have a schematic diagram for this power supply. The power supply looks the same as the AquaPower AQ11070W100 TB-SMPS-180W.

Hello my friend. The value of R16 is 1R0, 1 Ohm.

Can you please tell me the value of R20? It is a little down, near C14 and Z2.

Thank you.
