# Pay Terminal Issues

> Built-in hardware diagnostics and clear recovery steps keep your Pay Terminals taking payments.

This guide covers troubleshooting steps for the FlexWash Pay Terminal, including hardware diagnostics and recovery from common start-up errors.

## Hardware Diagnostics

If a Pay Terminal cannot read a customer's card, run the built-in hardware diagnostics to identify which reader is failing. The terminal can test the NFC antenna, chip card reader, and swipe reader independently.

<Steps>
  <Step title="Open Diagnostics">
    On the Pay Terminal, open `Settings` and tap `Diagnostics`.
  </Step>

  <Step title="Scroll to the Hardware section">
    The Hardware section lists the three card readers along with the battery status.

  </Step>

  <Step title="Test each reader">
    Tap a reader and follow the on-screen prompt. You will need a card to tap, insert, or swipe.

    <Tabs>
      <Tab title="NFC antenna">
        Tap a contactless card against the back of the terminal.

        </Frame>
      </Tab>
    </Tabs>
  </Step>

  <Step title="Confirm the result">
    A working reader reports a `Success` status. Any other result indicates a hardware fault with that specific component.

<Tip>
  If one reader fails but the others pass, customers can still pay using a different card method while you arrange a replacement. [Contact FlexWash Support](/technical/troubleshooting/contact-support) with the failing component name.
