2004 Marquis Reward "dr" error

(1/1)

sregnar:
I put a new heating element in my tub, and replaced the topside. Primes fine, then attempts to heat(temp reading ambient water 72) and it shuts off to a "dr" error. If I force start by pressing the jet button the tub runs 15 minutes and heat turns on and actually bumped the temp by 1 degree in 15 minutes. But come time for the tub to test and run to heat it shuts down again. I called balboa and he ran a few tests on the phone with me to confirm water flow to heater, and said admirer I should just order 2 new heater sensors. Any thoughts?

MarKee:
Have you tried running it without the filters in? Filter may be clogged. Also make sure the splice valves are open (handle pulled out)

sregnar:
Thanks, yes the filters are out and the valves are open. Here's a dumb question. 2 pumps, what does each do, and how can I be 100% sure they're working? I have a jet button that gives me 2 speeds, but that seems to be all from 1 pump. I hear both pumps running and both get warm, but one might be chugging along and is never know. That would give me a dr error I believe due to lack of flow.

MarKee:
Jets 1 usually controls Pump 1 which will be your filtration and heating pump.   

Most models have 2 speed pumps, but some will have a 2 speed pump and 1 single speed pump.

According to Marquis service manual the most likely causes for a "DR" code are as follows in this order:

Defective Pump
Low Water Level
Closed Slice Valve
Clogged Pump Impeller
Defective Sensor (Extremely Unlikely)
Defective PC Board (Extremey Unlikely)
