Q: Can landlord legally give a 72 hr notice on 4th day past due??

A: You are quite correct that he cannot lawfully serve a 72 hr notice until your rent is at least a full 7 days past due - and then it must be properly worded and lawfully served (text messages and email do NOT comply), and yes, if you pay the full amount due within the 72 hours, the landlord must accept it and has no grounds to evict. As for the thirty day for cause, it too has to be properly worded and lawfully served, and it has to give you 14 days to simply disconnect your washer and hook his up again and you get to stay. Further, you should demand that he immediately fix the washer and may be entitled to pay reduced rent until he does. Plus I am not at all sure a Judge would throw you out for using your own washer when the landlord won't fix the one supplied, assuming using yours is causing no damage. On top of that, while possible, I have never seen a lease that prohibits you from using your own washer and if it does not, you can hardly be liable for breaching it if you do use your own.

As for responding to him or telling him that he can't give you a 72 hr notice yet, you can but why would you? The longer he goes with not doing things right, the longer it is before he can legally terminate your tenancy and the more time you have to find a new place and make an orderly move. If he tries to remove you or actually gives you notices, consider reviewing it all with a landlord-tenant attorney to learn your exact rights and chart a course of action. If he files in court and you win, the landlord will owe you your court costs and attorneys fees so an attorney might represent you free, collecting their fees from the landlord, after having reviewed everything and determining the merit of your case.
