A Perth resident required immediate hospitalisation after the lid came off her Thermomix, splattering her body with scalding sauce that caused second-degree burns to her upper torso and arms.

Danika Jones’s burns are so bad that she now struggles to use a conventional oven because of the heat, and suffers lasting fears of being burnt.

“I had popped the pasta sauce ingredients in the Thermomix using the same recipe I’ve used every week since I bought the machine more than two years ago,” Ms Jones said, news.com.au reports.

She was taken to the hospital burns unit for extensive treatment and was given an electromagnetic device to wear for 20 hours each day as the burns healed.

The Thermomix – or “thermie”, as devotees like to dub them – is a German-designed multi-use appliance sold through private consultants for more than $2000 per machine. It can chop, heat, cook and puree a meal in one go, with minimal intervention required.

The TM31 model (which Jones’ owned) was recalled in October 2014. Jones took her machine in and had the seal replaced by the supplier, as per the recall.

It didn’t stop the lid coming loose and spraying Jones and her kitchen with a burning tomato pasta sauce .

“Towards the end of the process, it was pureeing the sauce when it started making a funny noise and vibrating,” she told news.com.au. “I walked over to turn it off and as I did that, it just exploded – the lid blew off and hot liquid went everywhere, all over me. The pain was intense.”

It’s not the first case of bad press for the machine, owned by Vorwerk. They were awarded a Shonky award by Choice consumer magazine for releasing a new model with no warning (and thereby reducing the value of just-purchased older models).

Jones is now suing Vorwerk, represented by law firm Slater and Gordon, and told media that hospital staff told her she was not the first burn-related Thermomix case they had seen. She hopes that her case will warn other families about the risk, and prompt a full recall of the model.

Through a media statement, Vorwerk said that Jones had declined their requests to examine the appliance.

“Since being made aware of this incident in January, Thermomix has been very cooperative in this case. We have made, and continue to make, every endeavour to work with Ms Jones to investigate this matter,” the statement read.

“Without a thorough investigation of the appliance, the manufacturer is unable to determine the cause of this incident. Unfortunately, on occasion the appliance can be used incorrectly.”
