Customer Question

Customer: Buderus GB142 boiler with a flashing P13 error message and no hot water or heat.
JA: Thanks. Can you give me any more details about your issue?
Customer: No.
JA: OK got it. Last thing – JustAnswer charges a fee (generally around $18) to post your type of question to HVAC Experts (you only pay if satisfied). There are a couple customers ahead of you. We can help you for less if you're not in a rush. Are you willing to wait a bit?
Customer: Can't sorry
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
