How much water in the bottom of a steriliser?

[THOMCATsForLifeNotJustForXmas]

I've got a handed down steriliser and have just de-scaled it etc ready to sterilise my breast pump bits etc. How many mls of water do you put in the bottom each time? And without any instructions is there anything else I should remember about them?

What make is it?

Is it a microwave one or plug in?

is it avent? 30ml rings a bell, but I may be hallucinating. How are you feeling love?

Actually if you have dish washer, just use that on the hottest cycle.
it'll do the same job.

this url has pdf file instructions for avent ones...

Hi the Avent microwave on is 200ml or 7oz.

This is for the quite big one that takes 4 bottle, with a blue rack, white bottom section and has a clear domed lid.

Cheers ladies, it's an Avent one, and 200 ml would make perfect sense, thanks for that.
Forgot about the dishwasher option, you're quite right, ahh well, I have both options available now.

Feeling good Bundle, thanks for asking, really good, lots of energy, tearing round like a mad woman and hoping baby will make an appearance this weekend, am due next Thursday but fingers crossed for earlier tbh.
