528599MP Genuine DishDrawer Mains Filter Board 230V for Fisher & Paykel Dishwashers DD603 DD6031 DD603MFD DS603 DS6031 DS603MFD

Fisher & Paykel's genuine 230V mains filter board for DD603 and DS603 DishDrawers is part 528599MP, and it also covers the DD6031 and DS6031 and the DD603MFD and DS603MFD. It replaces the earlier 525958MP, and 525958NP is linked to it as well, so if your old board carries either of those numbers, this is the current part. It's the RoHS compliant version.

DishDrawer dead or tripping power? Check the mains filter

The mains filter sits where power enters the dishwasher. It smooths out electrical noise and spikes before they reach the control electronics, and helps stop the dishwasher feeding interference back into your home's wiring. When it fails, the DishDrawer may be completely dead, power up only intermittently, or trip the safety switch as soon as it's turned on. Scorch marks, a swollen component or a burning smell near the filter point the same way. Water leaks onto the board are a common cause, so find and fix any leak at the same time.

Fitting the mains filter

Photograph the connections, fit the new filter in the same orientation and make sure the earth connection is secure.
