Repairing damaged MDF kitchen door.
Discussion
Kitchen cabinet door fronting integrated washing machine, MDF panel of door starting to both peel paint and bubble. I have removed both door and started to stripped paint off door, and attempted to sand where MDF has started to bubble.
I am not sure whether to continue with the same, or either to completely replace the MDF panel, or to cover the preset sheet of MDF with either a thin sheet of hardboard or plywood. With the replacing of the MDF involving breaking joints, i am a bit reluctant to go down the replacement route, so instead either continue with sanding and/or covering the MDF.

Are you sure the panel is a separate piece of wood to the frame, ie it's not all moulded/routed from one piece of MDF? If it is separate, instead of pulling the joints apart you could try cutting the rear of the rebate with a sharp knife and knocking the panel out. Then glue a new one in, but this would also depend on whether the original one is glued in to how difficult it will be.
Sand it back and fill if required with car filler.
Then when repainted DO NOT leave the dishwasher door ajar when the washing cycle has finished. It's the damp and heat escaping that Is causing your trouble.

Picture needed.
Thanks, I was hoping that you might reply to my post.Although only the paint on the washing machine cabinet had started to flake, my original intention was to have all the kitchen cabinets sprayed painted. Of the two companies i contacted, one wanted photos sent, and the other company representative that called in person, first gave an acceptable quote of £2k, and then declined the work.
Using the odd available hours over the last week or so, I have nearly managed to remove the paint from both sides of the door, with the MDF on one side "bubbling".
As I mentioned on my earlier post, i was considering either sanding the MDF, replacing or covering the MDF with another sheet material.
The paint I was going to use was Farrow & Ball's undercoat and topcoat.
Pictures I have taken of both sides of the door, Simpo Two has promised to post up for me.
You say it's an MDF door, but is there anything else on it bar the paint? If that's the case, paint straight on to MDF, then why is it flaking? What sort of paint is it? Is it the sort that is chemically hardened, a two-pack paint in other words?
I'm going to assume for the moment that it is two pack, that it's a mass produced kitchen and they didn't want to wait for water-based paint (such as Farrow and Ball and the other sorts intended for DIY use) to dry.
In fact, thinking about it, it must be because normal water based paints would not flake off.
So, if you can get the rest of the previous paint off then you are good to go. But if your intention is to simply remove the loose stuff and paint over the parts that haven't flaked then you will almost certainly be wasting your time, because the problem won't be cured, it will just have been painted over.
In that case, I suggest your buying new doors, have a look on eBay, they are amazingly cheap.

Carpentry is not my best subject, but was considering cutting out present panel, hoping that the same was not rebated, then cutting and fitting slightly oversized replacement panel.
Is there any use in sealing MDF, varnish etc., to avoid same contamination through moisture happening again?

Well unless my lamps really are that bad, what makes you think its MDF? It looks live some kind of either solid or veneered door. Is there any use in sealing MDF, varnish etc., to avoid same contamination through moisture happening again?
Was it not originally stained and then painted at a later date?
Yes, middle panel MDF.
After spending several hours sanding down panel's bubbles, thought MDF was ready for priming. Primed with primer/undercoat only for MDF fibres to lift on one side of panel.. Decided to purchase 2mm thick MDF, then cut slightly oversize, then glued to damaged side of panel. So far after priming, door looks good as new.
