bought a Sharp R-272M/800 W in November 2012. The base has started to bubble up and when pressed water comes out. Am I correct in saying I should no longer use the appliance?
Yes, you should stop using this appliance.

How bad is the bubbling?
Is there exposed metal work?

Customer: replied 4 years ago.

More bubbles appear as is it used. I cannot see any metal work. I haven't tried lifting the bubbles.

OK, thanks for that.

The liner is parting company from the cavity.
When the metal work becomes exposed, sparks will come from the waveguide cover.

The bubbling has most likely come from a spillage and a small bit of damage to the liner.
Future spillages have seeped under the liner, causing the bubbling whenever its heated.

Sorry, this is terminal for your machine.
There's no cure and it will need to be replaced, for hygene reasons as well as safety.

Let me know if you need more help with this.

Hope this helps

how could I have damaged the liner?

Sorry, I can't answer that.
Without seeing it at the very 1st bubble, I can only guess at the cause.

It only needs a scratch on the liner for water to get in.

I don't really understand. I have used a microwave for many years without any problems. I only bought the Sharp because my previous microwave had been in storage for over 12 months and it was old. I don't really know where to go to from here. Thank you for your advice.

You're welcome.

You could try using the sale of goods act against the retailer you purchased it from.
Normally, you need an independent engineer report to state it's inherent fault that was there from new.
Then, you'll get a partial refund.

Citizens advice can advise on this.

Customer: replied 4 years ago.

Thank you. All things considered I will buy a new microwave.

OK, thanks for letting me know.

Good luck with the replacement appliance.
