  If there's no hot water at the faucet in your MDC Caravan, several factors could be the reason: * The gas supply might be off or interrupted; check and turn it on if necessary. * The gas tank could be empty, so refill or replace it. * The appliance itself might be switched off; turn it on according to the operating instructions. * The fresh water supply might be turned off; open the fresh water supply. * The power supply to the appliance might be off; switch it on. * There may be a defect in the appliance. If LED 2 flashes red, it indicates a defect; in this case, contact a certified service technician.

Why is the hot water temperature too low in my MDC Caravan?
- D
  Donna ClarkAug 20, 2025
  If the hot water temperature is too low in your MDC Caravan, here are some potential causes: * The gas flow to the appliance might be too low (gas inlet pressure less than 10.5 in. wc). Consult your vehicle's documentation to see if the gas supply can provide the necessary gas volume. A service technician can verify the gas installation. * The hot water flow might be too high, or the cold water temperature reaching the appliance could be too low. Reduce the hot water flow at the faucet or shower. A certified technician can install a flow rate throttle in the water system. * There might be too much lime scale in the appliance. Decalcify the appliance. * The water pressure in the water system might be too high. Adjust the water pump pressure to a maximum of 65 psi (4.5 bar).

  Jason LeeAug 23, 2025
  If the yellow status LED 3 is off even when an operating mode is selected in your MDC Caravan, it could be due to: * The power switch being OFF, so switch the appliance ON at the POWER switch. * The power supply to the appliance being switched off, so switch on the power supply. * A power supply interruption. Reset by switching OFF at the control panel, waiting 2 seconds, and then switching it back on.

What to do if water is escaping at the pressure relief valve in my MDC Caravan?
- B
  Brittany VaughnAug 26, 2025
  If water is escaping at the pressure relief valve of your MDC Caravan, consider these possibilities: * If the water system is connected to a central water supply exceeding 65 psi (4.5 bar), install a pressure reducer at the fresh water supply. * If water cannot expand in the water system, contact the vehicle manufacturer about retrofitting a pressure compensation element. * If there is lime or dirt under the pressure relief valve seat, allow the appliance to cool, then slowly raise the test lever to flush the water system and try to force the debris out. You may need to replace the pressure relief valve; this should be done by a certified service technician.

What to do if water drips from the P&T safety valve in MDC Caravans?
- M
  Michael GriffinSep 2, 2025
  If water drips from the P&T safety valve in your MDC caravan, it could be due to excessively high water pressure or lime/dirt accumulation under the P&T safety valve seat. Check the water pressure, ensuring it doesn't exceed 400 kPa. If connected to a central water supply, use a pressure reducer. Allow the appliance to cool, then slowly raise the test lever to flush the system, attempting to dislodge any dirt. If the problem persists, a certified service technician may need to replace the P&T safety valve.

  If your MDC caravan heater operates for a prolonged time and then the red lamp lights up, it indicates the excess temperature thermostat has been triggered. Check the water level and refill if necessary, ensuring the drain valve is closed. To reset, switch off the appliance, wait 5 minutes, and then switch it on again.

What to do if MDC Caravans heater doesn't operate and the red lamp lights up?
- A
  Adam PaulSep 8, 2025
  If your MDC caravan heater does not operate when switched on, and the red lamp lights up after approximately 30 seconds, possible causes include a fitted cowl cover, air in the gas supply, no gas supply, or incorrect gas pressure. Remove the cowl cover and clear any obstructions. Inspect gas valves and the gas cylinder. To unlock and purge air, switch off the appliance, wait 5 minutes, and switch it on again.

Why hot water comes out when opening the cold water tap in MDC Caravans?
- C
  Charlotte RossSep 12, 2025
  If hot water comes out when you open the cold water tap in your MDC caravan, it could be that hot water is flowing back through the cold water supply or the non-return valve is faulty. Fit a non-return valve in the cold water supply.
