Reliability and heat were the main problems. Valves were fragile devices that, due to the relatively primitive way they were manufactured, failed pretty quickly. In addition to that, they gave off vast amounts of heat. This meant they needed expensive air-conditioning systems to keep their temperature down.
Probably rate of burnout and heat. But this was common to all vacuum tube computers, not just Colossus.

using valves
The use of valves on the Colossus, a World War II codebreaking machine, led to two main problems: reliability and heat generation. The valves were prone to failure, which could disrupt operations and necessitate frequent repairs, impacting the efficiency of codebreaking efforts. Additionally, the heat produced by the valves could cause overheating, further complicating the machine's operation and necessitating additional cooling measures.

The Colossus was built using thermionic valves, thyratrons, relays and stepping switches.The Colossus Mark 1 used about 1600 valves and the Colossus Mark 2 used about 2400 valves. After the Colossus Mark 2 was in production and use the single Colossus Mark 1 was briefly shutdown and upgraded to a Colossus Mark 2. Five of the ten Colossus machines also had a device called the "gadget" that aided in a process called "rectangling", the number of additional valves added to each of these enhanced Colossus Mark 2 machines is unknown.
The Colossus computer worked using one to two thousand thermionic valves.
The Colossus machine faced several issues with using valves, primarily due to their inherent limitations in reliability and speed. Valves were prone to failure and required careful calibration, making them less efficient for the high-speed computations needed for code-breaking. Additionally, the mechanical nature of valves introduced delays, limiting the overall processing speed of the machine compared to more advanced electronic components. This necessitated innovative engineering solutions to mitigate these challenges.
