Vinyl and plumbing’s issues kitchen

[tim120000]

We bought a 70s semi (ex Council ) and behind the dishwasher and washing machine there is a strong musty smell and the vinyl is all ripped. It also seems like the wall needs plastering . Would we need a whole new kitchen or just new vinyl ?
Also how to fill the massive hole where the pipe leaves the wall ? The whole area looks a mess and there’s water under the dishwasher which makes me think there is a leak somewhere

Thanks

The 15 milli pipework looks a bit of a pig's ear (not neat). Are those joints watertight?
Use tissue paper to see if it picks up any water droplets from the joints.

Are those flexes going through the wall?

You could fill the hole with expanding foam, trim so it is below the surface and make good with plaster.

Edited for additions.

can you step back an photo more of the wall and units/sink plumbing to the right .
an the other side of the hole in the wall - is ther a washing machine on the other side?
an outside at ground level?

do you have a gas cooker?is any of that pipwork gas pipe?

the plaster should be cut back 50mm from the floor contact.
can you operate the dishwasher while its out of position an see if it leaks?
does pipework stop the D/W from pushing all the way back under the work top?
thers obvious damp so maybe the plaster needs hacking off but where do you stop?

if the black rubberised stuff iscable its 60 to 70yrs old.
slide appliances on a square of hardboard or similar an you wont damage your floor covering.

a proper job would be to pull all the units and w/top from that wall an hack off all damp plaster . anto re-plumb an re-wire to modern standards.
nothin on the pics appears to have been clipped?
