We are in a rental house and it's not our washing machine. I ran a service wash on it about 10 days ago but for the past 3 days, every time the machine drains and the draining water bubbles away under the sink, a truly vile smell comes out throughout the ground floor. (I initally accused DH and the DCs but after futilely checking DD's nappy several times I realised it was the washing machine :).
Is the problem with the machine or the drains? Do I need to get a plumber out? Put drain cleaner down the sink? We hope (builders permitting) to be moving into our own house in about 5 weeks so it's not a long term problem for us but if the machine or the drains are about to implode I'd rather report it to the landlord now than leave it as a lovely surprise for the next tenant.
I feel I should clarify that I don't put poo in the washing machine or the kitchen sink! Any baby clothes with poo on are rinsed off in the loo before they go in the machine. In case it's relevant, I only use Fairy liquitabs in the machine, no powders and no conditioner.
If anyone can tell me why this is happening and what I ought to do about it, that would be most appreciated.
