hotpoint BWD129 leak

[isitworthowt]

Morning Folks
Have the above washer dryer which has developed a leak
this is happening as soon as water is in the drum and is leaking out of the bottom of the drum around a small posidrive screw.
This was loose so tightened it up -all ok for now - but any idea what it is for?

cheers

It holds the bollard in for the heater quite common

ok, thanks for the prompt reply , so no great deal just ensure it is kept tight then?
Quite a common leak source?

bollard for the heater - not sure I quite unedrstand?

It's a stub that holds the end of the heater in place to stop it banging around , only way I can describe it that it looks like a silver bolt that goes on the end of flat packed furniture and you twist it to lock the bolt on and it pulls the wood together that's wot it Looks like and the Heater slides on it.
