The Ace of Cups represents an opportunity for change and renewal. The card indicates that Maria has the opportunity to make a decision in terms of health, and she can decide whether to repair or buy a new washing machine. The card also suggests that whatever choice you make, it will prove to be positive and beneficial to Mary's health.

Reversed Justice shows an obstacle to the decision Maria has to make. The card indicates that Maria must face her own fears, uncertainties and inner conflicts before she can make a final decision. She also indicates that Maria should pay more attention to signals from her body and mind before making a decision.

The Six of Swords suggests that Maria should consider the pros and cons of both options before making a final decision. This card indicates that Maria should also consider whether she is ready to face the changes needed to carry out her choice of hers. It also suggests that Mary must be prepared to make sacrifices to achieve the desired health outcomes.

In conclusion, based on the reading of the three tarot cards, it seems that Maria should carefully consider both options - buy a new washing machine or repair the old one - and weigh the pros and cons before making a final decision. Given the meaning of the cards and the general orientation, it seems more likely that Maria will decide to buy a new washing machine than to fix the old one as this would be a significant step towards taking care of her health.
