MK sockets else Hager one also can. I usually go with MK, the internals are built better.
Schneider framed type, despite the name their frame sucks, easy to pop off.

There's two types of 13A sockets:
1. framed (with a pop on picture frame type)
2. frameless (1 piece) sockets.

MK S2757 is the picture frame one, after installation check frame logo which side up, hang it on top edge, with ur hand just chop chop the bottom corners in. (Flush fit to wall like wooden ruler thickness).

MK E2757 is the 1 piece frameless one. (Raised fit about phone thickness). This one no frame to worry about, nothing to pop loose.
About 4.60-5 bucks each on shopee.

Choice of framed or frameless is yours, dep whether u have next door switch to match height with, or this is standalone. If standalone, fuss free the E2757 cannot go wrong.

Should be no problem if all the looped sockets were installed by an electrician If there is an overload condition, the MCB at DB box will trip.

1. Before using a test pen, poke it inside a Live terminal (when power is still on) to check that the test pen works.
2. You just need to replace the sockets like-for-like, after turning off everything in the whole DB box before you start to open things up.
3. Before handling/touching any wires, also check again with test pen to confirm they are all unpowered just in case you have funny configurations like more than 1 DB box (in some places) or its actually powered from the neighbour's DB box.
4. Test again one more time to confirm sure. A second test never killed anyone. Lack of testing, well, they are no longer with us.

Nothing wrong with the wiring or socket if other appliances is working. Repair the washer or buy new.
