toxic washer help!

Hello

I have a strange problem that I don't understand and neither did my local washer repair guy.

When a wash is on the washer fumigates the whole house with soapy salty toxic taste/ smell!

I think we had sewer problem at the last house but I'm not sure if the dishwasher and the washer were the culprits. When I moved home recently I brought with me a house full of saturated belongings which have a hefty salt residue all over them it's been a nightmare as it causes a mist to hang in the air when it's disturbed! It's crazy and I don't know where all this salt has come from. As there was also a smell of sulphur sometimes and I connected this to the drains.

Now in the new house my washer is giving off a terribly strong salty soapy stink and we are breathing it in! If you open the windows more comes in from the drains as it flushes down it's so potent!

I really need my washer right now as most of my things need washing.

I've never heard if this happening to anyone before it's nuts! And I'm turning into a nutjob myself trying to sort it out! I've gotten rid of a lot of stuff to minimise it.

Also, behind the dishwasher at the old house it stank of the same potent soapy salty thing.

However, when the neighbours had a bath or did a wash my house was infected with like a spray and a stink of bath salts etc.

Is the something in the washer? It seems contaminated and gasses off when washing. It's not just a bit soapy either it fills the upstairs and leaves your mouth burning and soapy.

I'm flummoxed. I've done hot washes with no soap and I use non bio. I have used cheap washing powder once or twice. It's a fairly new black beko under a year old

Can anyone understand what has happened please I'd be very grateful.
