Thanks again, everyone,
1) Even if washer was provided without training, I quote a law that you have to inform the landlord and provide documentation (receipts) etc.

Quote - "Option three can work for small jobs, but involves many factors. A.R.S. § 33-1363, the "self-help" clause, permits you either to sue the owner for monetary damages if repairs are not done, or to do them yourself, deducting the cost out of the next month's rent. It is limited to small jobs that can be completed at a maximum cost of either one-half of your periodic rent, or $299.99, whichever amount is more.
The balance of this article addresses the repair elements of A.R.S. § 33-1363. The self-help provision stipulates that: prior notice must be properly given to the owner, allowing him the opportunity to remedy the conditions himself; a licensed contractor is the only person who may do the work; and specific follow-up documentation must be presented to the owner when the deduction is made"
2) What about "pest control" when we have signed agreement that states that it is tenant's responsibility, they also tried to do that and charging me for it.
