A friend just got a second-hand Hotpoint dishwasher (First
Edition DW21P). Doesn't look to have been used much, quite
clean all around. I called around to plumb it in.
I ran it through a cycle, but was concerned about its operation.
The fill level is quite a way below the heating element. I
noticed this because I opened the door when it started the main
wash, and some steam came out, even though the water had only
just started heating. Then I realised this was coming from the
surface of the exposed element, which gets sprayed, but is not
submerged. I presumed this was a fault and aborted the cycle.
Took off the side panel to look for a pressure sensor.
Instead, I found that it fills the machine from a water bottle
in the side, which it fills and syphons out 3 times to give 3
bottle loads of water in the machine, presumably to give a
measured quantity of water. I couldn't see what was counting
up the 3 bottles - it could be a pressure sensor, but I didm't
Anyway, to make sure the rest of the machine was working OK,
I ran another full cycle, but for the main wash and final
rinse (the two heated parts of the cycle), I manually topped
up the water to cover the element. It worked fine, but at the
end of the drying cycle, it was obvious that the element was
running with no water in the machine (water which drips on
it instaly boils away), presumably to provide the drying heat?
So this got me thinking - is it actually supposed to be able
to run above the water in normal operation?
It is mounted quite high up.
Can anyone else with one of these have a look inside during
the main wash and/or final rinse, and see if the water level
covers the element?
