I reckon that’s a current dump resistor going through the diode to protect that switching transistor. We can do a bit of back-calculating to guess the value...
240V, 3W, current = 0.0125A. Using V=IR, Resistance R is 19,200 Ohms
240V, 2W, current = 0.0083. Using V=IR, Resistance R is 28,915 Ohms
Assuming the multiplier stripe looks like it’s either red, brown or orange, it’s probably going to be orange based on those rough numbers. 22k, 3W resistor.
